Solution
A light ray, parallel to the principal axis, coming from a point on object AB is reflected from the surface of the mirror, it passes through the principal focus and the other ray striking normally to the mirror reflects back and passes through the center of curvature. These two reflected rays, when produced backward, coincide at a point where the image is formed. The image, A'B' is virtual, erect, and magnified in size.
