Does wavelength change during refraction?
In refraction of light, there always takes place bending of light. The bending of light takes place around normal. If light travels from one medium to another medium, then there is a change in wavelength of light. ... Since there is a change in wavelength and frequency does not change so speed also changes.
Does frequency change in reflection?
Reflection is the change in direction of light when it falls on some medium. ... Therefore, wavelength and frequency of the wave does not change in case of reflection.
