Refraction of light rays
Light waves may change direction at the boundary between two transparent materials. Refraction is the change in direction of a wave at such a boundary.
Which does not change during refraction?
When a ray of light passes from one medium to the other medium, the physical quantities related with this ray of light such as velocity, wavelength, amplitude, etc changes such that the frequency of the wave always remains the same. Therefore, the frequency of the light does not change on its refraction.
When light is refracted there is a change in its?
The frequency is the number of waves passing a fixed point in a given period of time. The frequency of the wave does not change. The frequency is only determined by the source. When light is refracted, there is a change in its wavelength and speed.
