Question

Define convex lens?​

Answer 1

Explanation:

A convex lens is a converging lens. When parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus. The distance between the principal focus and the centre of the lens is called the focal length.

Answer 2

Hello mate✌✌✌

A concave lens is a type of spherical lens that is thick at its centre and thin at its edges. It converges a beam of light to a point. So, it is called 'converging lens'.
