Who discovered the Scattering of light?

The correct answer is Option (2) → C.V. Raman

C. V. Raman discovered on 28 February 1928 that when light passes through a transparent substance, a small part of the scattered light comes out with a changed wavelength (colour). This kind of scattering is named the Raman effect after him. It won him the Nobel Prize in Physics in 1930, the first Nobel Prize in science for an Asian, and 28 February is celebrated in India as National Science Day.
