Focal length of a spherical mirror gives an idea of how strongly the light is converged or diverged.
Spherical mirrors works by following the principle of law of reflection which does not depend upon the nature of the material by which it is made .
But the focal length depends upon the Radius of Curvature of mirror .
R=2f
⇒f=R/2
