Question

A shopkeeper wanted to fix a mirror which will give a maximum view of his shop. What type of mirror should he use? Give reason.

Answer 1

Convex mirror

1. A mirror whose reflective surface is bent outside is called a convex mirror.
2. The image formed on a convex mirror is always upright and virtual.
3. The magnification of the convex mirror is less than 1. That's why the range of vision in a convex mirror is large than in other mirrors.
4. A convex mirror diverges the parallel lights that fall on it and allows the maximum view of the object.

Therefore, the shopkeeper should use a convex mirror. Because the range of vision in a convex mirror is large than in another mirror, it will give the maximum view of his shop.
