Question

State whether true or false:

A concave lens is commonly called converging lens.

• A. True
• B. False

Answer 1

The correct option is B False

Answer is B.

Concave lenses are thinner at the middle. Rays of light that pass through the lens are spread out (they diverge). Hence a concave lens is a diverging lens. When parallel rays of light pass through a concave lens the refracted rays diverge so that they appear to come from one point called the principal focus.
Hence, the statement is false.
