Question

Can a convex lens give diverging rays?

Answer 1

1. We know that A convex lens is known as a converging lens.
2. In some specific circumstances, a convex lens can give diverging rays, when a convex lens is placed inside a liquid of a refractive index greater than that of the material of the lens. Otherwise always gives a convergent ray.

Hence, a convex lens cannot give diverging rays.
