CV Raman Essay

CV Raman represented and contributed significantly to India's scientific community as he was well-versed in philosophical thought and had an exquisite attention to detail. His discovery of the Raman Effect changed the world of science and made him the first ever Indian to be awarded the Nobel Prize in Physics in 1930. Here are a few sample essays on ‘ CV Raman ’.

100 Words On Essay On CV Raman

200 words on essay on cv raman, 500 words on essay on cv raman.

Since his father taught physics and mathematics at AV Narasimha Rao College in Visakhapatnam, CV Raman was raised in an academic environment. Raman was a dedicated student. He enrolled in the Presidency College in Madras in 1902, and in 1904 he successfully completed his BA programme, earning first place and a gold medal in Physics. He received the highest honours when he earned his MA in 1907. His early studies in optics and acoustics—the two areas of study to which he devoted his whole professional life—were conducted while he was still a student. Raman's primary study was on musical instruments and acoustics, which helped him be elected as a fellow of the Royal Society in 1924.

Early Life | C. V. Raman was born in Madras Province, India on November 7, 1888 in Thiruvanaikoil, Tiruchirappalli. His full name was Chandrasekhara Venkata Raman. He was the son of Parvati Ammal and R. Chandrasekhara Ver. His father taught physics and mathematics at Presidency College in Madras. His early studies in optics and acoustics were conducted while he was still a student. Raman began working for the Indian Finance Department in 1907 after finding that a scientific career did not appear to give the best opportunities at the time. Raman found opportunities to do experimental research in the lab of the Indian Association for the Cultivation of Sciences in Calcutta, despite his office duties consuming the majority of his time.

Accomplishments | The advancement of science in India was influenced by the work of Indian physicist C. V. Raman. In 1930, he became the first Indian scientist to receive the prestigious Nobel Prize in Physics. His discovery is commonly referred to as the "Raman effect" or "Raman scattering," which is the inelastic scattering of a photon. He received numerous honorary doctorates and memberships in prestigious scientific institutions. He passed away in Bangalore on November 21, 1970, at the age of 82. In India, National Science Day is observed on February 28 every year to commemorate the day that Indian scientist Sir Chandrasekhara Venkata Raman discovered the Raman phenomenon.

CV Raman was the first Indian and Asian to be awarded the Physics Nobel Prize. Most importantly, he accomplished this while India was not well-known in the scientific community.

The Raman Effect

In 1928, while researching how light refracts in different materials, he discovered that when a transparent substance is lit by a beam of light of a particular frequency, a small amount of the light exits at right angles to the original direction, some of which is of a different frequency from the incident light. The energies connected to changes in rotational and vibrational states in the scattering material were named as Raman frequencies. In short, the Raman effect, discovered by C.V. Raman, occurs when light that shines through a material is scattered and its wavelength varies from that of the original incident light due to interactions with the molecules in the substance.

Academic Contribution

Raman received his knighthood in 1929, and in 1933 he relocated to the Indian Institute of Science in Bangalore to take over the physics department. He was appointed the Raman Research Institute's director there in 1947, and in 1961 he was elected a member of the Pontifical Academy of Science. He helped establish almost all Indian research institutions during his lifetime, founded the Indian Journal of Physics and the Indian Academy of Sciences, and mentored hundreds of students who went on to hold significant positions in academic institutions and government in India and Myanmar (Burma).

His Work and Achievements

After spending 15 years in Calcutta, he moved to Bangalore to work as a professor at the Indian Institute of Science (1933–1948), and in 1948 he was appointed director of the Raman Institute of Research, which he had founded and endowed. The Indian Association for the Cultivation of Sciences appointed him as Honorary Secretary. In 1926, he also started the Indian Journal of Physics, serving as its Editor. Raman supported the creation of the Indian Academy of Sciences and presided over it. He also served as the president of the Bangalore Current Science Association. Raman had produced credible work in his discipline, and the Indian Association for the Cultivation of Sciences published his early autobiographies. These addressed the maintenance of vibrations and the theory of violin-family musical instruments. He presented a paper on the "Molecular Diffraction of Light" in 1922, marking the beginning of a series of studies with his associates that eventually resulted in the discovery of the radiation effect, which bears his name. He won the 1930 Nobel Prize in Physics for this work. He and Suri Bhagavantam made the quantum photon spin discovery in 1932.

Raman lost consciousness in his lab at the end of October 1970. He pulled through and requested to be moved from the hospital to his institute's grounds. On November 21st, 1970, he passed away. His life served as an example of how hard work, dedication, and patience can lead to success. A new era of higher science began with him, and he set the example for others to follow.

500 Words Essay on CV Raman

Chandrasekhara Venkata Raman, popularly known as C.V. Raman, was an eminent physicist who left an indelible mark on the scientific landscape of India and the world. His groundbreaking work in the field of light scattering, known as the Raman Effect, earned him the Nobel Prize in Physics in 1930. He was the first Asian and non-white to receive a Nobel Prize in any branch of science.

Early Life and Education

C.V. Raman was born on November 7, 1888, in Tiruchirappalli, Tamil Nadu. He was a prodigious child and completed his schooling at a very young age. Raman graduated with a gold medal in Physics from Presidency College, Madras, in 1907. Despite his keen interest in science, he initially embarked on a career in the Indian Finance Department due to the lack of opportunities in the scientific field in India at that time.

The Path to Discovery

Raman’s passion for science never waned, and he carried out scientific research in his spare time. His first research paper on diffraction of light was published in 1906. In 1917, he got an opportunity to serve as the Palit Professor of Physics at the University of Calcutta. It was during his tenure here that he made his most significant discovery.

On February 28, 1928, Raman discovered that when light traverses a transparent material, some of the deflected light changes in wavelength. This phenomenon, now known as the Raman Effect, provided the foundation for Raman spectroscopy, a tool commonly used today for identifying the molecular composition of materials. This discovery was a significant leap in the field of quantum physics.

Nobel Laureate and Later Life

Raman was awarded the Nobel Prize in Physics in 1930 for his discovery. He was knighted in 1929 for his contributions to science. In 1943, Raman established the Raman Research Institute in Bangalore, where he served as the director and remained active in research until his death in 1970.

C.V. Raman’s legacy extends beyond his scientific contributions. He was a visionary who believed in the potential of scientific research in India. His life serves as an inspiration for aspiring scientists to pursue their passion relentlessly. In India, National Science Day is celebrated on February 28, the day Raman discovered the Raman Effect, to commemorate his contributions to the field of science.

C.V. Raman’s life and work exemplify the pursuit of knowledge and the power of curiosity. His groundbreaking research in the field of light scattering changed the course of scientific research and continues to have significant implications in various scientific fields. His story is not just about his scientific achievements but also about his commitment to nurturing scientific research in India.

C.V. Raman: The Raman Effect

C.V. Raman and the Raman Effect

International historic chemical landmark.

Designated December 15, 1998, at the Indian Association for the Cultivation of Science in Jadavpur, Calcutta, India.

Commemorative Booklet (PDF)

"I propose this evening to speak to you on a new kind of radiation or light emission from atoms and molecules." With these prophetic words, Professor C. V. Raman of Calcutta University began his lecture to the South Indian Science Association in Bangalore on March 16, 1928. Raman proceeded to describe a discovery that resulted from a deceptively simple experiment. Conducted far from the great centers of scientific research in the Western world, the results would capture the attention of scientists around the world and bring many accolades, including the Nobel Prize, to their discoverer.

Raman’s Fascination with Light Scattering

Raman Effect as the Chemist’s Tool

The Laser and Raman Spectroscopy

Biography of sir c.v. raman, further reading, landmark designation and acknowledgments, cite this page.

Educated entirely in India, C.V. Raman made his first trip to London in 1921, where his reputation in the study of optics and especially acoustics was already known to the English physicists J. J. Thomson and Lord Rutherford, who gave him a warm reception. Raman's specialty had been the study of the vibrations and sounds of stringed instruments such as the violin, the Indian veena and tambura, and two uniquely Indian percussion instruments, the tabla and the mridangam.

But it was the return trip from London to Bombay aboard the SS Narkunda that would change forever the direction of Raman's future. During the fifteen-day voyage, his restless and probing mind became fascinated with the deep blue color of the Mediterranean. Unable to accept Lord Rayleigh's explanation that the color of the sea was just a reflection of the color of the sky, Raman proceeded to outline his thoughts on the matter while still at sea and sent a letter to the editors of the journal Nature when the ship docked in Bombay.

A short time later Raman was able to show conclusively that the color of the sea was the result of the scattering of sunlight by the water molecules. Ironically, it was exactly the same argument that Rayleigh had invoked when explaining the color of the sky — the blue was the result of the scattering of sunlight by the molecules in the air.

Raman was now obsessed with the phenomenon of light scattering. His group in Calcutta began an extensive series of measurements of light scattered primarily by liquids but also by some solids. As a result, Raman was able to explain the blue color observed in the ice of Alpine glaciers.

“The Raman Effect” commemorative booklet

Analysis of light scattered by a liquid is not an easy task, and much of the early work in Calcutta was done by the visual observation of color rather than precise measurements of the light's wavelength as shown in Figure 1 at right. The fundamentals of Raman's crucial experiment are outlined in Figure 2.

The violet light of the solar spectrum is isolated with a violet filter and passed through the liquid sample. Most of the light emerging from the liquid sample is the same color as the incident violet beam: the so-called Rayleigh scattered light. However, Raman and K. S. Krishnan were able to show that some of the scattered light was a different color, which they could isolate by using a green filter placed between the observer and the sample. The advantage of using a visual observation is that several substances can be studied quickly. In his first report to Nature , titled "A New Type of Secondary Radiation," Raman indicated that approximately 60 different liquids had been studied, and all showed the same result — some scattered light had a different color than the incident light. "It is thus," Raman said, "a phenomenon whose universal nature has to be recognized."

The Raman Effect is a very weak effect; only one in a million of the scattered light particles, or photons, actually exhibits the change in wavelength. This explains, in part, why the effect was not discovered earlier. In all of the early light-scattering studies, the excitation source was sunlight, which Raman has described as being plentiful in Calcutta, but it still lacked the desired intensity. The acquisition in 1927 by the IACS of a seven-inch (18 cm) refracting telescope enabled Raman to condense the sunlight and create a more powerful light source for his studies. By early 1928, mercury arc lamps were commercially available, and he switched to this even more intense light source.

Raman knew that visual and qualitative observations alone would not be sufficient information. He methodically set out to measure the exact wavelengths of the incident and Raman scattering by replacing the observer with a pocket spectroscope. He ultimately replaced it with a quartz spectrograph with which he could photograph the spectrum of the scattered light and measure its wavelength. These quantitative results were first published in the Indian Journal of Physics on March 31, 1928.

The significance of the Raman Effect was recognized quickly by other scientists. Professor R. W. Wood of Johns Hopkins cabled Nature to report that he had verified Raman's "brilliant and surprising discovery ... in every particular. It appears to me that this very beautiful discovery which resulted from Raman's long and patient study of the phenomenon of light scattering is one of the most convincing proofs of the quantum theory."

Raman had also recognized that his discovery was important to the debate in physics over the new quantum theory, because an explanation of the new radiation required the use of photons and their change in energy as they interacted with the atoms in a particular molecule. Raman also knew that there was a more important result, remarking in his 1930 Nobel Prize address that "... the character of the scattered radiations enables us to obtain an insight into the ultimate structure of the scattering substance."

In the first seven years after its discovery, the Raman Effect was the subject of more than 700 papers in the scientific literature, mostly by physicists who were using the technique to study the vibration and rotation of molecules and relating those phenomena to the molecular structure. Then, as noted by Raman biographer G. Venkataraman, there was a decline in interest, as "the first bloom of novelty had worn off and physicists were satisfied that they understood the origin of the effect." At the same time, chemists became interested in the Raman Effect as an analytical tool. In James Hibben's words, "The Raman Effect became the adopted child of chemistry."

Raman Effect as a Chemist’s Tool

By the late 1930s the Raman Effect had become the principal method of nondestructive chemical analysis for both organic and inorganic compounds. The unique spectrum of Raman scattered light for any particular substance served as a "fingerprint" that could be used for qualitative analysis, even in a mixture of materials. Further, the intensity of the spectral lines was related to the amount of the substance. Raman spectroscopy could be applied not only to liquids but also to gases and solids. And unlike many other analytical methods, it could be applied easily to the analysis of aqueous solutions. It was a ubiquitous technique, giving information on what and how much was present in a plethora of samples.

The use of Raman spectroscopy as a basic analytical tool changed sharply after World War II. During the war, infrared spectroscopy was enhanced by the development of sensitive detectors and advances in electronics. Infrared measurements quickly became routine operations, while Raman measurements still required skilled operators and darkroom facilities.

Raman spectroscopy could no longer compete with infrared until another development in physics — the laser — revived Raman spectroscopy in a new form beginning in the 1960s.

Raman understood the need for more intense light sources to amplify the effect and observation of the scattered light. The laser provided an even more intense source of light that not only could serve as a probe exploring the properties of the molecule but could also induce dramatically new effects.

With the development of the Fourier transform (FT) technique and the application of computers for data handling, commercial FT-Raman spectrometers became available in the late 1980s, resulting in resurgence in the use of the original Raman Effect.

The new Raman spectroscopy has been used to monitor manufacturing processes in the petrochemical and pharmaceutical industries. Illegal drugs captured at a crime scene can be analyzed rapidly without breaking the evidence seal on the plastic bag. Chemists can watch paint dry and understand what reactions are occurring as the paint hardens. Using a fiber-optic probe, they can analyze nuclear waste material from a safe distance. Photochemists and photobiologists are using laser Raman techniques to record the spectra of transient chemical species with lifetimes as small as 10 -11 seconds. Surface-enhanced Raman spectroscopy is used for studying surfaces and reactions on surfaces. And, according to Kathy Kincade, Raman spectroscopy "has the ability to provide specific biochemical information that may foreshadow the onset of cancer and other life-threatening illnesses."

In his 1928 talk in Bangalore, Raman concluded, "We are obviously only at the fringe of a fascinating new region of experimental research which promises to throw light on diverse problems relating to radiation and wave theory, X-ray optics, atomic and molecular spectra, fluorescence and scattering, thermodynamics, and chemistry. It all remains to be worked out."

Seventy years later scientists are still actively working out the results and practical applications of Raman's deceptively simple experiment.

According to Hindu tradition, Raman was originally named Venkataraman after a Hindu deity, preceded by the initial of his father's first name, Chandrasekhara. In school his name was split to C. Venkata Raman, which later became C.V. Raman. With a father who was a professor of physics and mathematics and a mother who came from a family of Sanskrit scholars, Raman exhibited a precocious nature at an early age. He received a B.A. degree from Presidency College in Madras at the age of 16, placing first in his class and receiving a gold medal in physics.

While studying for his M.A. degree, he published his first research paper in Philosophical Magazine at the age of 18. It was the first research paper ever published from Presidency College.

Because of poor health, he was unable to go to England for further education. With nothing else available in India, in 1907 he passed the Financial Civil Service exam, married, and was posted to Calcutta as assistant accountant general.

Shortly after arriving in Calcutta, Raman began after-hours research at the Indian Association for the Cultivation of Science (IACS). In the first 10 years, working almost alone, he published 27 research papers and led the way for the IACS to become recognized as a vibrant research institute. Much of this early work was on the theory of vibrations as it related to musical instruments. After brief postings in Rangoon and Nagpur, he returned to Calcutta, took up residence next door to the IACS, and constructed a door that led directly into the institute, giving him access at any time. He received research prizes in 1912 and 1913 while he was still a full-time civil servant. He also increased the IACS reputation with his extensive lectures in popular science, holding the audience spellbound with his booming voice, lively demonstrations, superb diction and rich humor.

At the age of 29 he resigned from his lucrative civil service job when Sir Ashutosh Mukherjee, vice-chancellor, Calcutta University, offered him the Palit Chair Professorship. He continued to lecture even though it was not required, and he used the IACS as the research arm of the university. By the time of his first visit to England in 1921, his reputation in physics was well known. Three years later he was elected a Fellow of the Royal Society — only the fourth Indian so honored. That same year he toured the United States, spending four months at the California Institute of Technology through the invitation of Nobel Laureate Robert Millikan.

After discovering the Raman Effect in 1928, he was knighted by the British government in India and received the Nobel Prize in physics in 1930. Three years later, Raman left Calcutta for Bangalore, where he served as head of the Indian Institute of Science. There he continued his work on the Raman Effect and became interested in the structure of crystals, especially diamond. In 1934 he founded the Indian Academy of Science and began the publication of its Proceedings .

In 1948 he became director of the newly constructed Raman Research Institute, where he remained continually active, delivering his last lecture just two weeks before his death. His research interests changed in later years when he primarily investigated the perception of color.

Jagdish Mehra, a biographer, states, "Educated entirely in India, Raman did outstanding work at a time when the small Indian community worked almost entirely in isolation and few made science a career. In fostering Indian science, Raman emerged as one of the heroes of the Indian political and cultural renaissance, along with ... Mahatma Gandhi and Jawaharlal Nehru." But as Raman himself once said, outstanding investigators "are claimed as nationals by one or another of many different countries. Yet in the truest sense they belong to the whole world."

Landmark Designation

The American Chemical Society and the Indian Association for the Cultivation of Science dedicated The Raman Effect an International Historic Chemical Landmark on December 15, 1998 at the Indian Association for the Cultivation of Science in Jadavpur, Calcutta, India. The plaque commemorating the event reads:

At this institute, Sir C. V. Raman discovered in 1928 that when a beam of coloured light entered a liquid, a fraction of the light scattered by that liquid was of a different color. Raman showed that the nature of this scattered light was dependent on the type of sample present. Other scientists quickly understood the significance of this phenomenon as an analytical and research tool and called it the Raman Effect. This method became even more valuable with the advent of modern computers and lasers. Its current uses range from the non-destructive identification of minerals to the early detection of life-threatening diseases. For his discovery Raman was awarded the Nobel Prize in physics in 1930.

A short biography of C. V. Raman

Published by prakrsinha on January 19, 2021 January 19, 2021

A short biography of C. V. Raman: C. V. Raman or (Sir Chandrasekhar Venkata Raman), was born on 7 November 1888 Trichinopoly Madras presidency British India ( Tamil Nadu , India ). The innovative work of this legend from India, within the sphere of scattering of sunshine, earned him a reward in Physics in 1930.

Raman studied in St. Aloysius Anglo- Indian High school in Vishakhapatnam. Raman completed his metric education at 11 and intermediate at the age of 13 years in 1902. Raman joined Presidency College in Madras (now Chennai).where his father (Chandrasekhar Ramanathan Iyer) had been transferred to teach mathematics and physics. There Raman got a B.A. (Bachelorof Arts) degree from the University of Madras in Physics. There he was awarded a laurel wreath in physics, later in 1907 he completed his M.A. (Master of Arts) with the highest distinction.

His brother (Chandrasekhar Subrahmanya Ayyar ) joined The IFS (Indian Finance service) which is that the foremost honorable government service in India, which is now called Indian Audit and Account service. He started his career working in an exceedingly government sector, but in 1917 he left that job because at that time India wasn’t independent so Britishers weren’t supporting Raman to go further within the field of Physics, but after independence, in 1948 he founded his institute named “Raman research Institute where he did all his researches. Raman also contributed greatly to IACS (Indian Association of the cultivation of the science).

What is Raman Effect?

C.V. Raman was on a Ship, while he was going he saw that the color of the water is blue but he knew that water is transparent i.e. we can see through it and light can completely pass through it. After coming from the trip he did research on it and he found the reason behind this and later it was called Raman Effect.

Raman scattering, change in the wavelength of light that occurs when a light beam is deflected by molecules or atoms. When a beam of light transverse a dust-free, transparent sample of a chemical compound a little fraction of the light emerges in directions other than that of the incident (incoming).His effect is feeble in liquid compound. A short part, however, has wavelengths different from that of the incident light; its presence is a result which is called Raman Effect.

Awards and Honors

He was given Curzon Research Award in (1912), while he was working in Indian Finance Services.
He was awarded Franklin Medal in (1941), in Franklin Institute which is in Philadelphia.
In 1954 he was awarded Bharat Ratna.
In 1957, he was awarded the Lenin Peace prize
In 1930, he received the Hughes Medal of the Royal Society.
In 1928, he received the Matteucci from the Academia in Rome.
In 1930, Chandrasekhar Venkata Raman was given Nobel Prize in Physics. He was given this award because he has Discovered the “Raman Effect of Scattering of light’’. Before him, Rabindranath Tagore was awarded Nobel Prize in Literature.

He experienced a major heart attack at the end of October in 1970, while he was working in a laboratory. After this major heart attack, he was referred to a hospital where he lived for few days, he refused to stay there further and when he was counting his last breathe he arranged a meeting with the professors of his institute. And he died in the garden of Raman research institute.

C V Raman Biography

Writing a Biographical Essay of a Historical Figure

Sir Chandrasekhara Venkata Raman, was an Indian physicist who won the Nobel Prize in Physics in 1930 for his work on light scattering and the discovery of a new form of scattering called Raman scattering or the Raman effect. The compositions of solids, liquids, and gases can all benefit from this effect. It can also be used to diagnose diseases and track manufacturing processes.

Biography is an account of a person’s life by another person. It is a descriptive work written in detail. Biographical pieces can be in various forms, like a video or book and they can be of any length, like a book or an essay. An authorized biography is written with the permission of the subject and an unauthorized one is not. However, biographies of historical figures written for purely academic purposes do not require consent from the subject or people who hold the rights of consent for the subject.

Choosing the Right Level

Biographies can be written by students of all classes. The higher the class, the more details go into the essay. The biography by a fifth-grader will be smaller and less detailed than that written by a ninth-grader. The demand for making it more interesting and decorating it with aptly placed figures of speech grows with grade.

Choosing the Right Source

Biography is not fiction or a made-up story. It is the arrangement of boring dates and facts into a beautiful landscape that would be the subject’s life. For the facts to be accurate and true, trustworthy sources must be consulted, like a known book or reliable websites that contain life information.

Choosing the Right Information

Having selected the right source of information, it can get mind-boggling to choose what information to keep and what not to mention in the essay. It is better to have too much information than too little so that the best out of them can be chosen. A biography should answer some basic questions about the person. The place and date of his birth and death. Information about his immediate family. Important milestones of his life, like schooling, occupation, marriage, kids, appointments, or discoveries. His accomplishments during his lifetime. And then the legacy he leaves behind, like his impact on society or education and the historical significance.

How to Arrange the Information?

Biographies are descriptions of someone’s life, so setting the tone and making it sound interesting relies freely on the writer’s shoulders. The student can make life sound fun and lively, or gripping and intense. This is where the talent of a writer shines through, so use all of the writing tools at hand and make the best of them.

The Person Behind the Facts

The personality of the subject should shine through the essay. Select appropriate adjectives to build upon the character of the person. If interesting anecdotes highlight the kind of person he was, use them to build upon his personality.

Legacy in Conclusion

The achievement of his life and his notable works need to be mentioned, as well as how he affects posterity. In conclusion, the importance of his work and legacy should be highlighted.

It should be remembered that however tempting it feels to include interesting details and fun facts, the word limit should be kept in mind. This is what should rule which facts go and which do not in the essay. The introduction, body, and conclusion need to be clearly arranged. A biographical essay is not a story-telling spree, so the spirit of an essay should be intact.

The best essays are easy to read and the flow from one part to another is seamless. It might sound contradictory to keep a seamless flow while keeping the three parts of an essay demarcated, but it is not impossible and this is the delicate balance that can only be achieved by persistent practice. Language is not much different from Maths or Science in this aspect – practice makes perfect.

About C V Raman’s Family and Background

Chandrasekhara Venkata Raman was born to a Tamil Brahmin family in Tiruchirapalli, Tamil Nadu, on November 7, 1888. Raman's forefathers were agriculturists who settled in the Tanjore district near Porasakudi Village and Mangudi. Chandrasekhara Iyer, his father, attended a school in Kumbakonam and graduated with honours in 1881. He eventually earned a Bachelor of Arts degree in Physics from Tiruchirapalli's Society of the Promotion of the Gospel College in 1891. In the same college, Chandrasekara became a lecturer. He married Parvathi Ammal after passing the Matriculation exam and they had eight children: five sons and three daughters. Chandrasekaran, Raman's father, moved to Visakhapatnam when he was four years old to work as a lecturer at Mrs. A.V. Narasimha Rao College. He taught Physics, arithmetic, and physical geography at the university. Chandrasekaran was regarded as physically and mentally powerful due to his involvement in athletics, physical culture, and Indian Carnatic music, among other things. Raman, unlike his father, was not physically powerful, but he was a brilliant thinker. He excelled in school and displayed early signs of exceptional ability, receiving praise from his teachers as well as numerous prizes and scholarships. While still in school, Raman developed an interest in Physics. He once designed a dynamo on his own and was fascinated with how physical principles and machines worked. C. V. Raman graduated from high school at the age of eleven, receiving first place in the Matriculation Examination (top marks). He then enrolled in the AVN College to prepare for the Intermediate Exam. He received more accolades this time, and he received top scores on the university test. In 1903, he received a scholarship to study for a BA degree at the Presidency College in Chennai (then Madras), where he was the youngest student. At the time, the Presidency College was the best in Southern India. When Raman was in college, the majority of his professors were Europeans. Raman's interest in Physics grew even stronger during this period, and he also developed a strong liking for English. Raman earned first place in the university's BA exams in 1904, and gold medals in English and Physics. Raman's teachers encouraged him to continue his education in England, but the Madras Civil Surgeon refused, arguing that the young Raman was too weak to endure the English climate. Raman, on the other hand, completed his MA in Physics at Presidency College and did not travel abroad until he was thirty-three years old.

About C V Raman’s Early Career and Marriage

In January 1907, Raman sat for and passed his Master's examination, earning top marks and a slew of awards and prizes. While he desired to focus on science (particularly research), there were no research opportunities in India (specifically for Indians). Owing to his deteriorating health at the time, he was unable to travel to England. As a result, Raman's thoughts turned to work for the government, which is known to be clean, stable, and even prestigious. Even in this situation, he desired to enter the prestigious Indian Civil Service (ICS), the highest level of government service, but this meant training in England and taking the exam there—an option that was also ruled out due to medical reasons. The Financial Civil Service (FCS), where Raman's brother C.S. Iyer was already a member, which was his next preference. The FCS served as a forerunner to today's Indian Audit and Accounts Service. Raman passed the FCS examination in 1907 and married Lokasundari before taking up an official job. This period of his life unfolded unusually. Typically, parents arranged Indian marriages, which includes finding a suitable horoscope match for their infant. This included looking at the positions of the stars on their birth date, as well as other horoscopic statistics. The boy and his parents then pay a visit to the girl's house to see if she likes them; during this period, the girl is normally asked to give a musical performance. The date for their marriage is fixed if all arrangements are in agreement and the girl's family provides adequate dowry. Raman's marriage went in a different direction. Mr. Ramaswamy Sivan, a freemason, theosophist, and radical thinker, was a friend of Raman's as a college student. Mr. Sivan's house was a frequent stop for Raman, and one day he heard music from an Indian classical instrument, the veena, played by Lokasundari, Sivan's sister-in-law, who was visiting from Madurai. Lokasundari was a natural at playing the veena, and Raman was instantly drawn to her. Sivan discussed this idea with Raman, who immediately accepted it since Lokasundari was of marriageable age at the time and her family was looking for a suitable groom. Raman then continued to seek permission from his parents. However, it was later discovered that Lokasundari, thought of the same caste as Raman (Brahmin), belonged to a separate subset—a match that was strictly forbidden at the time. Raman's father, who is a rather liberal man, agreed that Raman could choose his bride, even if she came from a different subset. The rest of the family, including Raman's mother, was unhappy, however. Despite these challenges, Raman followed his heart and kept on doing things his way. In mid-1907, Raman was appointed Assistant Accountant-General in Calcutta, even though he was still a teenager. His pay, including the marriage allowance, was Rs. 400 at the time. Raman and Lokasundari set out for Calcutta, the capital of British India at the time. Raman took advantage of Calcutta's vibrant and scientific environment, allowing him to fully articulate his scientific creativity—Calcutta was then regarded as the East's premier science city. Raman was sent to Nagpur and Rangoon in addition to Calcutta; no matter where he was posted, Raman still found a way to perform experiments at home.

C V Raman Contribution to Science

Raman productively used the time he had with Professor Jones while studying Physics at Presidency College, designing and creating experiments to address the boundless questions he had. Only the most basic laboratory instruments (enough for classwork) were available in the Physics lab at the time, but Raman made use of them all. Raman's questions were frequently those for which there were no answers in the literature. As a result, the nature of science came naturally to him, prompting him to perform experiments throughout his life. Raman experimented with asymmetric diffraction of light though he was well aware of light in a wave shape and the principle of diffraction. Professor Jones was given his observations on this experiment, which he collected and gave to him for feedback. Professor Jones, on the other hand, remained silent for many months. Raman was aware of the Philosophical Magazine at the time, possibly those subscribed to by the Connemara Public Library, which was about five kilometers from Presidency College (it is not certain how Raman came to know of this magazine). This paper was written in 1906, and Raman, who was only 18 at the time and had not yet graduated from high school, was the sole author with no acknowledgments. Raman's achievement was all the more remarkable because Presidency College was not a research institution, and Raman's paper was the first to emerge from there. Almost immediately after Raman's first publication, Johns Hopkins University's R.W. Wood published another. Wood later sent a cable to Nature announcing the Raman Effect's discovery. Raman left the government in 1917 to take up the newly established Palit Professorship in Physics at the University of Calcutta. Simultaneously, he continued his study at the IACS, where he eventually rose to the position of Honorary Secretary. Raman referred to this period in his career as his "golden age." At the IACS and the University of Calcutta, he was surrounded by a group of gifted students. In 1929, he presided over the 16th session of the Indian Science Congress. Raman worked on the acoustics of musical instruments in addition to his Nobel Prize-winning work on light scattering. Based on superposition velocities, he developed a theory of transverse vibration of bowed strings. In comparison to Helmholtz's method, this does a great job of describing bowed string vibration. He was also the first to explore the harmonic essence of Indian drum sounds like the tabla and mridangam. Raman was appointed director of the newly established Indian Institute of Science (IISc) in Bangalore in 1933. The IISc was established in 1909 with the aim of conducting original research and providing science and engineering education. Before Raman's appointment, all of IISc's directors, as well as the majority of its faculty, were British. He remained a Professor of Physics for another two years. The new government of Independent India named him the country's first National Professor in 1947. In 1948, he retired from the Indian Institute of Science and a year later founded the Raman Research Bangalore, Karnataka, where he served as director until he died in 1970.

C V Raman’s Discovery

Raman was awarded the Nobel Prize in Physics in 1930 for his research on light scattering and the discovery of the Raman effect. The inelastic scattering of a photon is known as "Raman scattering" or "Raman effect." This phenomenon is the basis for Raman spectroscopy.

What led to C V Raman’s Invention of Raman Effect?

C V Raman Discovery of the Physics of Musical sound- Understanding the Physics of musical Sound was one of Raman's passions. The Sensations of Tone by Hermann Von Helmholtz, which he came across when he entered IACS, inspired him. Between 1916 and 1921, he researched and published a lot of his observations. Based on the superposition of velocities, he developed the principle of transverse vibration of bowed string instruments. The wolf tone in violins and cellos was one of his earliest experiments. He investigated the acoustics of various violins and related instruments, as well as water splashes and Indian stringed instruments. "Experiments with mechanically-played violins" was one of his works. C V Raman Discovery behind the Blue colour of the sea- In 1919, Raman began investigating light scattering as part of his broadening foray into optics. His first amazing discovery was the mechanics of seawater's blue colour. In September 1921, he reflected on the Mediterranean Sea's blue colour while sailing home from England on the S.S. Narkunda. He tested the seawater with basic optical instruments, including a pocket-sized spectroscope and a Nicol prism. No.56 Lord Rayleigh's explanation in 1910, "The much-revered dark blue of the deep sea has little to do with the colour of water, but is the blue of the sky seen by refraction," was the strongest of many theories on the colour of the sea. C V Raman Inventions: Most photons are elastically dispersed as light is scattered from an atom or molecule. The incident photons have the same energy (frequency) as scattered photons, and therefore the same wavelength. Excitations of optical frequencies distinct from, and normally lower than, the frequency of the incident photons scatter a small fraction of scattered light (roughly one in ten million photons). Raman scattering may occur in gas when a molecule's vibrational, rotational, or electronic energy changes. "The character of scattered radiations allows us to obtain an insight into the ultimate structure of the scattering," Raman explained. Raman published his thesis on "Molecular Diffraction of Light" in 1922, the first of a series of investigations with his collaborators that eventually led to his discovery of the radiation effect that bears his name (on February 28, 1928). In 1928, C. V. Raman and K. S. Krishnan, as well as Grigory Landsberg and Leonid Mandelstam, independently identified the Raman effect. Raman's discovery was hailed by physicists as evidence of the quantum theory. The vibrational Raman effect is of primary interest to chemists. The Raman Effect was named a National Historic Chemical Landmark by the American Chemical Society in 1998, in recognition of its importance as a method for studying the structure of liquids, gases, and solids. The Raman Effect is distinct from the fluorescence mechanism. The incident light is completely absorbed in the latter case, and the system is transferred to an energetically excited state from which it can only transition to various lower states after a certain period (resonance lifetime). Both processes emit a photon with a different frequency than the incident photon, and the molecule is brought to a higher or lower energy level. However, the Raman Effect can occur for any frequency of incident light, which is a significant difference. The Raman Effect, in contrast to the fluorescence effect, is not a resonant effect.

Born at Trichinopoly in Tamil Nadu on 7th November, 1888, his father was a lecturer in Mathematics and Physics, in Mrs AV Narasimha Rao College, Visakhapatnam, and later joined Presidency College, Madras. His maternal grandfather was a Sanskrit scholar, well versed in ‘navya nyaya’ or modern logic.

So, from an early age, he was immersed in an academic atmosphere. He was a diligent student. He entered the Presidency College, Madras, in 1902, and in 1904 passed his BA examination, winning the first place and a gold medal in Physics. In 1907, he gained his MA degree, obtaining the highest distinctions. His earliest researches in optics and acoustics—the two fields of investigation to which he dedicated his entire career were carried out while he was a student. Since at that time a scientific career did not appear to offer the best possibilities, Raman joined the Indian Finance Department in 1907. Though the duties of his office took most of his time, Raman found opportunities for carrying on experimental researches in the laboratory of the Indian Association for the Cultivation of Sciences at Calcutta.

In 1917, he was offered the newly endowed Palit Chair of Physics at Calcutta University, and decided to accept it. Raman’s main research was focussed on acoustics and musical instruments, and led to his election as fellow of the Royal Society in 1924. It was during a trip to England in 1921 that he was fascinated by the blue colour of the Mediterranean.

With a very simple experiment, he convinced himself that the blue colour of the sea was not only due to the reflection of the sky, as proposed by Lord Rayleigh, but mainly due to the scattering of light by water molecules. On his return to Calcutta, he began a systematic study of the scattering of light by different liquids, culminating in the discovery of a totally new kind of radiation, predicted by the quantum theory and named after him.

There Raman radiations carry vital information about the internal structure of the scattering molecules, and have proved to be of immense importance in studying molecular structures. His efforts finally paid off when he was awarded the Nobel Prize in Physics in 1930, the first to be ever won by an Indian. Thereafter, he became the Honorary Secretary of the Indian Association for the Cultivation of Sciences. After 15 years in Calcutta, he became Professor at the Indian Institute of Science at Bangalore (1933-1948) and in 1948, he became the Director of the Raman Institute of Research at Bangalore, established and endowed by himself. He also founded the Indian Journal of Physics in 1926, of which he was the Editor.

Raman sponsored the establishment of the Indian Academy of Sciences and served as its President since its inception. He was also the President of the Current Science Association, Bangalore, which publishes Current Science. (India)

Raman has done credible work in his field and his early memoirs appeared as Bulletins of the Indian Association for the Cultivation of Sciences. These dealt with the maintenance of vibrations and the theory of musical instruments of the violin family. In 1922, he published his work on the ‘Molecular Diffraction of Light’, the first of a series of investigations with his collaborators which ultimately led to the discovery, on 28th February, 1928, of the radiation effect, which is named after him. This work bagged him the 1930 Nobel Prize in Physics.

Some other investigations which propelled the world of science during his time were the experimental and the theoretical studies on the diffraction of light by acoustic waves of Ultrasonic and Hypersonic frequencies. In 1932, he and Suri Bhagavantam discovered quantum photon spin. During his term at IISc, he admitted the talented electrical engineering student, GN Ramachandran, who went on to become a recognised X-ray crystallographer.

This luminous star in the firmament of the scientific fraternity has been honoured with a large number of honorary doctorates and memberships of scientific societies. He was elected as a fellow of the Royal Society in 1924 and knighted in 1929. In 1941, he was awarded the Franklin Medal. In 1954, he was conferred upon, the Bharat Ratna. He got the Lenin Peace Prize in 1957.

Another big honour was that the American Chemical Society and IACS recognised his discovery as an International Historic Chemical Landmark. India celebrates National Science Day every year on 28th February to remember the discovery of Raman effect that took place in 1928.

At the end of October, 1970, he collapsed in his laboratory. Doctors gave him four hours to live. He survived and asked to be shifted from the hospital to the gardens of his institute. He passed away on 21 st November, 1970. His life was a testimony to hard work, patience and perseverance for achieving one’s goals. One should also be level headed and not go overboard on attaining success. With him, dawned an era of high quality science, and he showed the light for others to follow.

ADVERTISEMENTS:

Read this comprehensive essay on Chandrasekhar Venkata Raman (1888 A.D. – 1970 A.D.) !

The Great Indian physicist Chandrasekhar Venkata Raman, popularly known as C.V Raman, was born on 7 th November, 1888 at Trichirapalli in Tamil Nadu. His father was a physics teacher and so it was natural that Raman developed love for this subject. He was a brilliant student from the very beginning. As a brilliant and promising lad, he passed his matriculation examination at the young age of 12 from Madras University.

His parents wanted to sent him England for higher studies but his poor health did not allow it. He studied at Hindu College, Visakhapatnam and Presidency College, Madras. He obtained his post-graduation degree in physics in 1907 with the top position. During his student period he conducted many researches and published his papers in many reputed magazines.

His interest in physics was deep and lasting and so he continued his research work in his spare time in the laboratory of the Association. He published his research results in the leading journals of Calcutta, now Kolkata which were in regard to the subject of propagation of light. These original research papers were of great scientific significance.

When these came to the notice of the then Vice -Challenger of Calcutta University, Sir Ashutosh Mukharjee, he appointed him Professor of physics in the University. During his stay at the University he continued his research with much more devotion and won immense honour and recognition as a physicist.

He was elected the Fellow of the Royal Society of London in 1924. He discovered the “Raman Effect” in 1928. For it he was awarded the Nobel Prize for Physics in 1930. He became the first Indian to win this prestigious honour. With this award, his reputation increased by leaps and bounds and many Universities and institutions of repute honoured him with Ph D and D.Sc. degrees.

In December, 1927 he was busy in laboratory when the news came that the well-known physicist A.M. Compton was awarded the Nobel Prize for demonstrating that the nature of X-rays undergoes a change when passed through a matter.

This effect came to be known as the “Compton Effect.” Encouraged by this discovery, Raman continued his experiments and ultimately proved that light rays can also be scattered. His discovery enabled for the first time, the mapping of possible levels of energy gains of molecules and atoms of a substance and thus discovered their molecules and atomic structure. This discovery of the scattering of light led to the development of a simple alternative to infra-red spectroscopy, namely, Raman Spectroscopy.

Raman Effect happens when molecules of a medium scatter light energy particles known as photons. The spectrum varies with the nature of the transparent medium used to scatter the light. Raman Effect has proved to be of great scientific value and with its help the structure of more than 200 compounds has been known. He also gave us the scientific explanation for the blue colour of the sky and the ocean.

He explained that the blue color of the ocean was as a result of the scattering of sunlight by the molecules of the water. He travelled widely abroad delivering lectures about his discoveries and researches. In 1933 he became the Director of the Indian Institute of Sciences, Bangalore. In 1943 he founded the Raman Research Institute at Bangalore. He was knighted in 1927. He was awarded the Bharat Ratna in 1954 and the International Lenin Prize in 1957.

Raman was a born genius and a self-made man and scientist with deep religious convictions. His interests were wide and deep and so were his contributions to the human knowledge and development. Besides optics, he was deeply interested in acoustics—the science and study of sound.

His contributions to the mechanical theory of bowed, stringed and other musical instruments like violin, sitar, cello, piano, veena, Tanpura and mridangam have been very significant. He explained in detail how these musical instruments produce harmonious tones and notes. He died on November 21, 1970 at the ripe age of 82 at Bangalore and his mortal remains were consigned to flames in the campus of the Raman Research Institute.
