Question

DefIne power of lens....​

Answer 1

Explanation:

Power of lens is the ability of the lens to converge the rays of light falling on it. It can also be defined as P=1/f where f is the focal length. ... One Dioptre is the power of a lens whose focal length is 1 metre. Convex lens has positive power while concave lens has negative power......
