C. V. Raman Sir Chandrasekhara Venkata Raman (7 November 1888 – 21 November 1970) was an Indian physicist born in the former Madras Province in India presently the state of Tamil Nadu, who carried out ground-breaking work in the field of light scattering, which earned him the 1930 Nobel Prize for Physics. He discovered that when light traverses a transparent material, some of the deflected light changes wavelength. This phenomenon, subsequently known as Raman scattering, results from the Raman effect In 1954, India honoured him with its highest civilian award, the Bharat Ratna.At the end of October 1970, Raman collapsed in his laboratory, the valves of his heart had given way. He was moved to the hospital and the doctors gave him four days to live.
