Passage: Sir Chandrashekhara 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 and amplitude. This phenomenon, subsequently known as Raman scattering, results from the Raman effect. In 1954, the Indian government honoured him with India's highest civilian award, the Bharat Ratna.
