Question

A convex lens has a divergent action and a concave lens has a convergent action.

पर्याय

• True

• False

Answer 1

This statement is False.

Explanation:

Convex lenses have a convergent action, not a divergent action. They converge parallel incident rays of light to a focal point after refraction, hence they are often called converging lenses. 

Concave lenses, on the other hand, have a divergent action. They diverge parallel incident rays of light as if they are coming from a virtual focus point hence they are often called diverging lenses.
