Answer 2

Answer:

1. A concave lens can be regarded as made of a very large number of portions of triangular prisms.

2. The bases of these prisms are towards the edges of the lens, i. e., away from the central thinner portion of the lens.

3. A ray of light passing through a prism bends towards its base.

Hence, a concave lens is called diverging lens.

Explanation:

1. Concave lens :

A lens having both spherical surfaces curved inwards is called a concave lens or double concave lens or biconcave lens.

2. It is thicker at the edges than in the middle.
