Question

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?

Prabhat Rajore · Accepted Answer

Air is the rarer medium and water is the denser medium. The ray of light travelling in air while entering obliquely into water slows down and bend towards the normal. The reason is, light travels faster in rarer medium as compared to in denser medium.   - Wired Faculty
