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 ?

Explanation

The light ray 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. Water (1.33) is optically denser than air (1.0003), a ray of light travelling from air into the water will bend towards the normal.
