Chandrasekhara Venkata Raman, ordinarily known as C.V. Raman was perhaps the best physicist of India and the world. He was brought into the world on November 7, 1888, in Tamil Nadu. CV Raman had an enormous impression on Physics by finding what is known as the “Raman Effect.” He received a Nobel Prize for defining “what is Raman Effect” in 1930. He graduated from the University of Madras, where he topped the exam at 16. Raman then completed his master’s from the same university with the highest distinction in 1907. He was also rewarded with the Highest Civilian Award of India, Bharat Ratna, in 1954.
The phenomenon of scattering of light has always fascinated Raman from earlier days. This became his strength, and he discovered the Raman Scattering Effect or the Raman Effect.
What Is Raman Effect?
The ‘Raman Effect’ explained the scattering of light by the molecules of the medium through which light travels. It was observed that the light changes its wavelength when a beam of light gets deflected by the molecules of the medium. As the incident ray is sent from one side of the transparent dust-free medium, the light emerges out from the other end in another direction than the incident ray.

Unpopular Facts About C.V. Raman And What Is Raman Effect
- He was elected as the first Indian director who served IIS (Indian Institute of Science) in 1933. It was a proud moment as an Indian as all the previously appointed Directors were Britishers at IIS.
- Raman found that the photons of light exhibit angular momentum while he was with his students at a class in 1932.
- He also served the Indian Finance Services as Assistant Accountant General, where he got access to Indian Association for the Cultivation Science in Calcutta. There he began his research work and contributed two optics and acoustics. He was just 19 when he joined the IFS.
- Raman became the first National Professor of independent India after 1947 when India became independent.
- While working as a Professor in IACS in Calcutta, he performed several independent experiments over the scattering of light, which eventually led to the development of Ramen’s spectroscopy.
- He collaborated with KS Krishna in the year 1928 in IACS. The experiment in which they worked together gave them the conclusion of the Raman Effect. This is how Raman explained what the Raman effect is.
- In 1948 he also studied the optical behavior of various crystals, including diamond and other iridescent substances. His spectroscopy gave a new approach to crystal dynamics.
- In 1929 Ernest Rutherford gave Raman’s Effect for the Royal Society’s Presidential Address. Raman won the Knight Bachelor Award. Later, he was honored with the Fellow of the Royal Society Award.
- He introduced his research institute known as Raman Research Institute situated in Bangalore, where he worked as the Director till his death in 1970.
Conclusion
Raman was a prodigies child since his childhood. He completed his intermediate at the age of 11 with the highest distinction. He also supported several students while he was a professor at the University of Calcutta, and groomed students with science and its miracles. Therefore, the day when Raman explained his Raman effect to the world, i.e. February 28 is celebrated as National Science Day countrywide.
