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?

Answer:

A ray of light when it travels from air to water it bends towards the normal.

When a ray of light travels from an optically rarer medium to an optically denser medium, it gets bent towards the normal.As water is  more optically denser than air, a ray of light travelling from air into the water will bend towards the normal.
