Answer: The correct option is (B) " Refraction "
Explanation :
The light shows many phenomena like reflection, refraction, diffraction, interference etc.
The refraction of light is one of them. When light rays travel from one medium to another, the light ray bends away from the normal or towards the normal because of the differences in refractive indices of media.
Also, there is a change in the direction of light when it goes from one medium to another.
So, refraction of light is the correct option.
