Sir C.V. Raman (Chandrasekhara Venkata Raman)(1888 - 1970)
Nobel Prize for Physics (1930)
C V Raman was born on 7th Nov. 1888 in Thiruvanaikkaval, in the Trichy district of Tamil Nadu. He finished school by the age of eleven and by then he had already read the popular lectures of Tyndall, Faraday and Helmoltz.
He acquired his BA degree from the Presidency College, Madras, where he carried out original research in the college laboratory, publishing the results in the philosophical magazine. Then went to Calcutta and while he was there, he made enormous contributions to vibration, sound, musical instruments, ultrasonics, diffraction, photo electricity, colloidal particles, X-ray diffraction, magnetron, dielectrics, and the celebrated "RAMAN" effect which fetched him the Noble Prize in 1930. He was the first Asian scientist to win the Nobel Prize. The Raman effect occurs when a ray of incident light excites a molecule in the sample, which subsequently scatters the light. While most of this scattered light is of the same wavelength as the incident light, state (i.e. getting the molecule to vibrate). The Raman effect is useful in the study of molecular energy levels, structure development, and multi component qualitative analysis.
