Question

why concave and convex mirror are called as converging and diverging mirror respectively

Answer 1

Dear Student,

When parallel light rays fall on the surface of convex mirror then after reflection those rays seem to meet (diverge) at a single point but actually they do not meet. So, it is called diverging mirror.

When parallel light rays fall on the surface of a concave mirror, all the rays after reflection converge(meet) at a single point(focus). Hence, a concave mirror is also called a converging mirror.
