Question

A convex lens can be regarded as a set of prisms and a glass slab, such that refracting angle of the prisms:

पर्याय

• continuously decreases in outward direction

• continuously increases in outward direction

• remains same in outward direction

• none of these

Answer 1

Continuously increases in outward direction

Explanation:

A convex lens acts like prisms whose refracting angles increase towards the edges. So the angle does not decrease or remain the same outward.
