Energy

Vedclass · Answer

(A) The energy of a photon is given by the relation $E = h
u$,where $h$ is Planck's constant and $
u$ is the frequency of the photon.When a photon travels from one medium to another,its frequency $
u$ remains constant because it is determined by the source of the light.Since the frequency does not change,the energy $E$ of the photon also remains unchanged.Conversely,the velocity,wavelength,and momentum of the photon change when it enters a denser medium like glass from air.

When a photon enters glass from air,which one of the following quantities does not change?
