Question

A ray of light goes from water into air. Will it bend towards the normal or away from the normal ?​

Answer 1

Answer:

When a ray of light travels from a denser medium (water) to a rarer medium (air), it bends away from the normal. Therefore, the ray of light will bend away from the normal in the given case.

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.
