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?

When a ray of light travels from air into water obliquely, it bends towards the normal. This is because water is optically denser than air. On entering water, speed of light decreases and the light bends towards normal.

The best ray of light travels from the air into water obliquely and towards the normal for more water is optically denser than air.
It is the speed of light decreases and entering water for light bends towards normal.
This light ray rarer medium and water from the denser medium as well as travelling from rarer to a denser medium show the refraction of light from air to water.
