AB is the principal axis of a spherical mirror. I is the point image corresponding to a point object O. Choose the correct opritons.
What is the principal axis of a spherical mirror ?
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.
Define the principal focus of a spherical mirror.
A point light source lies on the principal axis of concave spherical mirror with radius of curvature 160 cm. Its image appears to be back of the mirror at a distance of 70 cm from mirror. Determine the location of the light source.
