Statement-1: Position of image approaches focus of a lens, only when object approaches infinity, Statement-2: Paraxial rays incident parallel to principal axis intersect at the focus after refraction from lens.

Rays Not Parallel To Principle Axis

We know that parallel light rays which are inclined to the principal axis of a spherical mirror, after reflection converge at a point in the focal plane of the mirror. With this knowledge explain how you will trace the reflected ray for incident ray PQ shown in the Fig. F is focus and C is centre of curvature of the mirror.
