Question

Define convex lens why is it referred to converging lens

Answer 1

hi

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.

hope it helps (:

Answer 2

A convex lens is thicker in the middle than at the edges. a convex lens half parallel rays converges to the principal focus due to which the convex lens is known as converging lenses respectively
