RAMAN EFFECT

In 1921 Sir C.V.Raman was on a ship one day coming back from London when a question struck him. Why is the sea really blue?. He wasn't convinced with the notion that it's blue because of the sky's colour. So in March 1928, he published a theory which states that 'The change in the wavelength of light that occurs when a light beam is deflected by molecules' known as the 'Raman Effect'.
