Sir C.V. Raman won the Nobel Prize in Physics in 1930 for his work on:
Answer:
The scattering of light
He discovered that when light traverses a transparent material, some of the deflected light changes wavelength. This phenomenon is known as the Raman effect.
60809
Which scientist won the Nobel Prize in Physics in 1918 for the discovery of energy quanta?
Answer:
Max Planck
Max Planck is considered the father of quantum theory. His discovery that energy is emitted in discrete units (quanta) won him the prize.
