Dr.Chandrasekhara Venkata Raman ( 7 November 1888 – 21 November 1970) was an Indian physicist who made ground-breaking works in the field of light scattering. With his student K. S. Krishnan, he discovered that when light traverses a transparent material, some of the deflected light change wavelength and amplitude. This phenomenon was a new type of scattering of light and was subsequently known as the Raman effect (Raman scattering).The day is celebrated by the Government of India as the National Science Day every year in commemoration of the discovery. His works earned him the 1930 Nobel Prize in Physics and was the first Indian or Asian or non-white person to receive Nobel Prize in any branch of science.
