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. Since water is optically denser than air, a ray of light travelling from air into the water will bend towards the normal.

Answer 2

Hi mate

Here is the answer

When a light travelling in air enters water obliquely then=

1)It enters from rarer to denser medium

I.e air to water.

2)So the velocity of light entering decreases.

3)This results in bending of light rays towards NORMAL.
