A light ray is incident on the wall of a glass tank as shown below. Draw a rough diagram of the path of the light ray as it passes through the glass tank and the water and emerges again into air. Draw the normal at each interface.

State two laws of refraction of light.

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?

A pencil partially dipped in water appears bent. Which of the following explains this phenomenon?

Assertion (A): When light enters from air to glass, it bends towards the normal. Reason (R): Glass is a rarer medium than air.

Draw a ray diagram showing the path of rays of light when it enters with oblique incidence (i)from air into water; (ii) from water into air.
