(a) The magnification of a concave mirror is - 1. What is the position of the object? (b) The magnification of a spherical mirror is `+-`2. What kind of mirror can it be?

Text Solution

Verified by Experts

(a) The object must be at the centre of curvature of concave mirror. The image formed is real, inverted and of the same size as the object. That is why magnification = - 1.
(b) The mirror must be a concave mirror. Only then magnification can be positive or negative.
