C V Raman (E)
This film is based on Sir CV Raman's work. One day, in the summer of 1921, Raman was on the deck of a ship in the Mediterranean Sea en route to the Congress of Universities of the British Empire at Oxford. He looked at the beautiful blue color of the Mediterranean Sea and began to doubt Rayleigh’s explanation of its color. Rayleigh had correctly explained that the sky looks blue because of a phenomenon now called Rayleigh scattering. The Raman effect is a very small effect compared with Rayleigh scattering. Only about 1 in ten million photons undergo inelastic scattering. Raman and his colleague K.S. Krishnan reported their discovery in March 1928 in 'Nature'. Raman was awarded the 1930 Nobel Prize in Physics for his work on the scattering of light and for the discovery of the effect named after him.
