Question Question 1
A ray of light travelling in air enters obliquely into water. Does the light ray bend towards the normal or away from the normal? Why?
The light ray bends towards the normal because when a light ray enters from an optically rarer medium (which has a low refractive index i.e., air) to an optically denser medium (which has a high refractive index i.e., water), its speed slows down and it bends towards the normal.
