Question

a ray of light enters obliquely into water from air. how does the ray of light bend in this case? state the reason behind it
​

Answer 1

Explanation:

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.

Answer 2

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.
