SIR C V RAMAN ( 1888 - 1970 )
C.V.Raman is the first Nobel Scientist of India. He won Nobel Prize in 1930 in physics for his discovery “Raman Effect”.
Chandrashekara Venkata Raman was born on November 7, 1888 at Tiruchinapalli. He was the son of college teacher. He did his M.A. at Presidency college in Chennai. He took up an administrative job in the Finance Ministry in Kolkatta. His interest in science made him to become a member of the Indian Institute for cultivation of science.
He studied acoustics. He went to London on a lecture tour. On his return journey he was fascinated by the blueness of the sky and sea. He questioned himself why were they blue. He found and concluded that the blueness was due to the scattering of light by water molecules. He wished to prove his theory. He did research in optics. In 1924 he was elected FRS. London for his contribution to optics.
He discovered the scattering of light and later it was named Raman effect. This was discovered on 28 February 1928. He was awarded Nobel Prize. In 1943 he founded his own institute in Bangalore, the Raman Research Institute. He continued his research till his death on November 20, 1970. He worked earlier in Indian Institute of Science, Bangalore.
The Raman effect is important in understanding the molecular structure of chemical compounds. It is the Phenomenon that causes changes in nature of light when it is passed through a transparent medium whether solid, liquid or gaseous.
February 28, annually is being celebrated as National Science day in India.
