remains same

Vedclass · Answer

(A) When a light wave travels from a rarer medium to a non-reflecting and non-absorbing medium,the total energy it carries remains the same.Energy in a light wave is proportional to the frequency of the wave and the number of photons present.Since the frequency of light remains constant when it changes mediums and the medium is non-absorbing (no energy loss) and non-reflecting (no energy diverted),the total energy is conserved.

The total energy carried by a light wave when it travels from a rarer to a non-reflecting and non-absorbing medium:
