Giants in History: Sir Chandrasekhara Venkata Raman

Sir Chandrasekhara Venkata Raman (7 November 1888 – 21 November 1970) was an Indian physicist who performed ground-breaking research in the field of light-scattering. He is best known for discovering that when light passes through a material, some of the deflected light changes wavelength and amplitude – a phenomenon which became known as Raman scattering. The principles of Raman scattering and the Raman effect are applied in Raman spectroscopy, a technique widely used for analysis and identification of materials. For his pioneering work, Raman was awarded the Nobel Prize for Physics in 1930.
