Point `S^(')` is the image of a point source of light S in a spherical mirror whose optical axise is `N_(1)N_(2)` (shown in Figure). Find by construction the position of the center of the mirror and its focus.

The position of optical axis N_(1)N_(2) of a spherical mirror, the source and the image are known (as shown in Figure ). Find by construction the positions of the center of the mirror, its focus, and the pole for the cases a. A-source, B-image, B-source, A-image.

A ray of light parallel to the principal ads of a spherical mirror falls at a point M as shown In the figure.Identify the type of the mirror used in the diagram

By means of plotting find : (a) the path of a light ray after reflectin from a concave and convex spherical mirrors (see Fig. where F is the focal point, OO' is the optical axis) , (b) the positions of the mirror and its focal point in the cases illunstrated in Fig. where P and P ' are the conjugate points.
