What is the minimum distance between the object and its real image formed by a concave mirror and when is it possible ?

Text Solution

Verified by Experts

The minimum distance between the object and its real image is zero when u = v = 2f, i.e., the object is placed at the centre of curvature of the concave mirror.

The focal length of a concave mirror is 30 cm. An object is placed at a distance of 45 cm in front of the mirror. A plane mirror is placed perpendicularly on the principal axis of the concave mirror in such a way that the object is situated in between the two mirrors. Light rays from the object at first are reflection from the concave mirror and then from the plane mirror. As a result the final image coincides with the object. What is the distance between the two mirros?
