Question

the radius of curvature if a sherical mirrior of focal length f cm is

​

Answer 1

Answer:

It is given that the radius of curvature of a spherical mirror is given as R=20 cm. We know that if the radius of curvature is positive then the spherical mirror is a convex mirror. We know that for a spherical mirror the focal length is half the radius of curvature of the mirror, that is R=2f.
