When light travels from a rarer to a denser medium, the speed decreases. Does the reduction in speed imply a reduction in the energy carried by the light wave?

Dear student

When a light wave travel from a rarer to a denser medium, its speed decreases but energy carried by the wave remains constant. It depends on the amplitude of wave. The frequency also remains constant.
