Answer 2

Sir Chandrasekhara Venkata Raman[1] (/ˈrɑːmən/;[3] 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.[4] In 1954, India honoured him with its highest civilian award, the Bharat Ratna.[5][6]
