Rays from the sun subtend an angle theta (in radians) at the pole of a convex mirror (in radians) at the pole of a mirror of focal length f. If the diameter of the sun is D ,then diameter of the image of the sun formed by the mirror is:
(a) f theta
(b) 2 f theta
(c) 6 f theta
(d) none of these
Please tell what would be the case if the mirror is plane.
