उत्तर
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 passing through the center of curvature strikes the mirror normally i.e. 90 degrees. Hence it will reflect back. These two reflected rays coincide at a point between F and C, where the image is formed. The image, A'B' is real, inverted, and diminished in size.
