Question

Two big mirrors A and B are fitted side by side on a wall. A man is standing at such a
distance from the wall that he can see the erect image of his face in both the mirrors.
When the man starts walking towards the mirrors, he finds that the size of his face in
mirror A goes on increasing but that in mirror B remains the same:
(a) Mirror A is concave and mirror B is convex
(b) Mirror A is plane and mirror B is concave
(c) Mirror A is concave and mirror B is plane
(d) Mirror A is convex and mirror B is concave

Answer 1

Mirror A is concave and mirror B is convex

Explanation:

When an object is placed anywhere between infinity and Pole in front of A convex mirror, the object has a definite size. Initial position of man is between infinity and Pole

In concave mirror, when the object is between Centre Of Curvature and Focus, image is enlarged and object is between Focus and Pole, image is highly enlarged.

So the initial position of the man was in the Centre Of Curvature of Concave mirror
