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.

1928 മുതൽ സി വി രാമ‌ന് നോബൽ സമ്മാനത്തേക്കുറിച്ച് പ്രതീക്ഷയുണ്ടായിരുന്നു. രണ്ട് വർഷത്തിന് ശേഷം രാമൻ പ്രഭാവം എന്ന കണ്ടുപിടുത്തത്തിന് അദ്ദേഹത്തിന് നോബൽ സമ്മാനം ലഭിച്ചു. നവംബറിൽ നോബൽ സമ്മാനം വാങ്ങാനായി ജൂലൈയിൽ തന്നെ അദ്ദേഹം സ്വീഡ‌നിലേക്കുള്ള ടിക്കറ്റ് ബുക്ക് ചെയ്തിരുന്നു.

ആദ്യ ഏഷ്യക്കാരൻ

ശാസ്ത്രത്തിനുള്ള നോബൽ സമ്മാനം നേടിയ ആദ്യത്തെ ഏഷ്യക്കാരൻ മാത്രമല്ല, വെള്ളക്കാരനല്ലാത്ത ആദ്യ വ്യക്തികൂടിയാണ് സി വി രാമൻ.

ക്വാണ്ടം ഫോട്ടോൺ സ്പിൻ

1932 ൽ രാമനും സൂരി ഭാഗവന്തവും ക്വാണ്ടം ഫോട്ടോൺ സ്പിൻ കണ്ടെത്തി. ഈ കണ്ടെത്തൽ പ്രകാശത്തിന്റെ ക്വാണ്ടം സ്വഭാവം തെളിയിക്കാൻ കൂടുതൽ സഹായകരമായി.

കടലിന്റെ നീലിമ

1921 ൽ യൂറോപ്പിലേക്ക് പോകുമ്പോൾ അദ്ദേഹം കണ്ട, മെഡിറ്ററേനിയൻ കടലിന്റെ അത്ഭുതകരമായ നീല നിറമായിരുന്നു അദ്ദേഹം കണ്ടെത്തിയ ഒപ്‌റ്റിക്കൽ തിയറിക്ക് പ്രചോദനമായതെന്ന് അദ്ദേഹം പറഞ്ഞിരുന്നു 

പ്രകാശത്തിനൊപ്പം ശബ്ദവും

പ്രകാശത്തെക്കുറി‌ച്ചുള്ള പഠനത്തിൽ മാത്രമല്ല രാമൻ ശ്രദ്ധ പതിപ്പിച്ചത്. ശബ്ദശാസ്ത്രത്തിലും അദ്ദേഹം പരീക്ഷണം നടത്തി. ഇന്ത്യൻ ഡ്രമ്മുകളായ തബല, മൃതംഗം എന്നിവയുടെ ശബ്ദത്തിന്റെ സ്വരചേർച്ചയേക്കുറിച്ച് പഠനം നടത്തിയ ആദ്യത്തെ വ്യക്തികൂടിയാണ് സി വി രാമൻ

തപാൽ സ്റ്റാമ്പ്

1954 ൽ ഭാരത് രത്‌ന സമ്മാനി‌ച്ചാണ് അദ്ദേഹത്തെ രാജ്യം ആദരിച്ചത്. അദ്ദേഹത്തിന്റെ ആദ്യ മരണ വാർഷികത്തിൽ ഇന്ത്യൻ തപാൽ വകുപ്പ് സർ സി ​​വി രാമന്റെ സ്മരണയ്ക്കായ് സ്റ്റാമ്പ് പുറത്തിറക്കിയിരുന്നു

National Science Day: The Raman Effect, which CV Raman won the Nobel for

In 1986, the government of india designated february 28 as national science day, to commemorate the announcement of the discovery of the “raman effect”. here is more about cv raman and his groundbreaking discovery..

In 1986, the Government of India, under then Prime Minister Rajiv Gandhi, designated February 28 as National Science Day to commemorate the announcement of the discovery of the “Raman Effect”.

This was the discovery which won physicist Sir CV Raman his Nobel Prize in 1930. Conducting a deceptively simple experiment, Raman discovered that when a stream of light passes through a liquid, a fraction of the light scattered by the liquid is of a different colour. This discovery was immediately recognised as groundbreaking in the scientific community, being the subject of over 700 papers in the first seven years after its announcement.

What is the “Raman Effect”? Why is it so important? Most importantly, who was the man behind this momentous discovery?

A young prodigy conducting after-hours research

Raman was born to a family of Sanskrit scholars in Trichy (present-day Tiruchirapalli) in the Madras Presidency in 1888. At the age of only 16, He received a BA degree from Presidency College in Madras, and was placed first in his class. While studying for his MA degree, at the age of 18, he got published in the Philosophical Magazine: this was the first research paper ever published by Presidency College.

Due to his ill health, he was unable to travel abroad for further education. Thus, in 1907, he got married and settled down in Calcutta as an assistant accountant general. While still a full-time civil servant, Raman began after-hours research at the Indian Association for the Cultivation of Science (IACS). Raman raised the profile of IACS, doing some award-winning research as well as conducting public demonstrations with charisma. At the age of 29, he finally resigned from his civil services job and took up a professorship in Presidency College, Calcutta.

A voyage across the ocean leads to interest in the scattering of light

By 1921, CV Raman had gained a solid reputation as a top scientific mind both in India and in the West. That year, he made his first journey to England. It was on the return journey that Raman would make an observation that would change his life and science forever.

While passing through the Mediterranean Sea, Raman was most fascinated by the sea’s deep blue colour. Dissatisfied with the then-accepted answer (“the colour of the sea was just a reflection of the colour of the sky”), his curious mind delved deeper.

He soon found out that the colour of the sea was the result of the scattering of sunlight by the water molecules. Fascinated by the phenomenon of light-scattering, Raman and his collaborators in Calcutta began to conduct extensive scientific experiments on the matter – experiments that would eventually lead to his eponymous discovery.

The Raman Effect

Simply put, the Raman Effect refers to the phenomenon in which when a stream of light passes through a liquid, a fraction of the light scattered by the liquid is of a different colour. This happens due to the change in the wavelength of light that occurs when a light beam is deflected by molecules.

In general, when light interacts with an object, it can either be reflected, refracted or transmitted. One of the things that scientists look at when light is scattered is if the particle it interacts with is able to change its energy. The Raman Effect is when the change in the energy of the light is affected by the vibrations of the molecule or material under observation, leading to a change in its wavelength.

In their first report to Nature, titled “A New Type of Secondary Radiation,” CV Raman and co-author KS Krishnan wrote that 60 different liquids had been studied, and all showed the same result – a tiny fraction of scattered light had a different colour than the incident light. “It is thus,” Raman said, “a phenomenon whose universal nature has to be recognised.”

Raman would go on to verify these observations using a spectroscope, publishing the quantitative findings in the Indian Journal of Physics on March 31, 1928.

The importance of the discovery

CV Raman’s discovery took the world by storm as it had deep implications far beyond Raman’s original intentions. As Raman himself remarked in his 1930 Nobel Prize speech, “The character of the scattered radiations enables us to obtain an insight into the ultimate structure of the scattering substance.” For quantum theory, in vogue in the scientific world at the time, Raman’s discovery was crucial.

The discovery would also find its use in chemistry, giving birth to a new field known as Raman spectroscopy as a basic analytical tool to conduct nondestructive chemical analysis for both organic and inorganic compounds. With the invention of lasers and the capabilities to concentrate much stronger beams of light, the uses of Raman spectroscopy have only ballooned over time.

Today, this method has a wide variety of applications, from studying art and other objects of cultural importance in a non-invasive fashion to finding drugs hidden inside luggage at customs.

C. v. raman: essay on c. v. raman (760 words).

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.

Essay on CV Raman : (Brief Essay)

CV Raman was the first person to receive a Nobel Prize from Asian country. He received the honor for his work on discovery of the Raman Effect and scattering of light. Nobel Prize is one of the greatest honor and recognition for a scientist.

CV Raman alias Chandrasekhara Venkata Raman was born in 8 November, 1888 in Chennai (then, Madras). He is the only Nobel Laureate from India, to be awarded the Nobel Prize in physics. His father was a lecturer in Visakhapatnam, where he did his schooling. Raman joined the Financial Civil Services at Calcutta in 1907, as an Assistant Accountant-General.

Later in his life, he conducted various experiments as a great physician. He was the man behind the ground-breaking work of discovering Raman Effect. He also expelled experiments in the field of light scattering. All of these earned him the 1930 Nobel Prize for Physics. He received the Nobel prize in a record time of two years, because of the practical significance of his discovery.

His discovery:

Raman discovered that when a beam of light traverses on transparent material, the deflected light is bound to change its wavelength. This phenomenon was subsequently called Raman scattering. He added that light donates some amount of energy to the interacting molecule, causing changes in color. This was known as the Raman Effect. This Raman spectroscopy is used in various laboratories to identify molecules and analyze living cell/tissues.

Apart from the Nobel Prize, Rama was honored with the highest civilian award of India, the Bharat Ratna in 1954. Raman died of a heart disease at the age of 82 in Bangalore, 1970.
