Question

A light ray moving into air from water will bend towards the normal.

• A. True
• B. False

Answer 1

The correct option is B False

1. Optically rare medium is the one in which light can travel at a fast rate.
2. Optically dense medium is the one in which light travels slowly.
3. When the light travels from one medium to another, its speed changes and so does the path.
4. When a ray of light travels from an optically denser medium to a rarer medium, it bends away from the normal.
5. So, when a light ray is moving from water (dense medium) into air(rare medium), it will bend away from the normal.

Therefore, the given statement is false.
