Choose the correct option:
Which property of light does not change when it travels from one medium to another ?
The correct option is B frequency
Color and energy depend on frequency and frequency does not change. The light photons are the same as the photons at the beginning . Frequency is a parameter of the source of emission of light, not the medium it is travelling through.
Therefore , When light travels from one medium to another medium which is separated by a sharp boundary , the frequency does not change.
