Question

the focal length of a spherical mirror is 100cm. state the type of mirror used and find its radium of curvature

Answer 1

As we know that R(radius of curvature)= 2f

So,R=2×100cm= 200cm

Hence radius of curvature is 200cm

The nature of the spherical mirror depends on it focal length.

If focal length is negative then nature of the spherical mirror is concave and if focal length is positive then it's nature is convex.
