C. V. Raman

Chandrasekhara Venkata Raman ( RAH-muhn; IAST: Candraśēkhara Veṅkaṭarāmaṉ; 7 November 1888 – 21 November 1970) was an Indian physicist known for his work in the field of light scattering. Using a spectrograph that he developed, he and his student K. S. Krishnan discovered that when light traverses a transparent material, the deflected light changes its wavelength. This phenomenon, a hitherto unknown type of scattering of light they called modified scattering, was subsequently termed the Raman effect or Raman scattering. In 1930, Raman received the Nobel Prize in Physics "for his work on the scattering of light and for the discovery of the effect named after him" and became the first Asian and non-White person to receive a Nobel Prize in Physics. Born in the Indian state of Tamil Nadu, Raman was a precocious child, completing his secondary and higher secondary education from St Aloysius' Anglo-Indian High School at the ages of 11 and 13, respectively. He topped the bachelor's degree examination of the University of Madras with honours in physics from Presidency College at age 16. His first research paper, on diffraction of light, was published in 1906, while he was a graduate student. The next year he obtained a master's degree. He joined the Indian Finance Service in Calcutta as Assistant Accountant General at age 19. There he became acquainted with the Indian Association for the Cultivation of Science (IACS), the first research institute in India, which allowed him to carry out independent research and where he made his major contributions in acoustics and optics. In 1917, he was appointed the first Palit Professor of Physics by Ashutosh Mukherjee at the Rajabazar Science College under the University of Calcutta. On his first trip to Europe, seeing the Mediterranean Sea motivated him to identify the prevailing explanation for the blue...
