Solution
The correct option is D Assertion is incorrect but Reason is correct Concave mirrors are capable of forming both real and virtual images. For a concave mirror in air, the magnitude of the focal length is equal to the radius of curvature of the mirror divided by two. i.e., f=R2, where R is the radius of curvature.
