Question

In a.................... lens , incident rays appear to diverge from the principal focus? ​

Answer 1

Answer:

concave lens

is the lens which diverge rays from focus

Answer 2

Answer:

Hope it helps you!

Explanation:

A convex lens is also called converging lens as the parallel beam of light rays passing through it converges at a single point.This point is known as principal focus of a concave lens. Thus refracted rays appear to diverge from the focus. Concave lens is opposite to convex lens.
