Question

You are given three mirrors:- concave, convex and plane. How will you indentify them without touching them?

Answer 1

If you look into a plane mirror, you can find that the size of the image is same as that of the object. If you look into a concave mirror, you can see an enlarged image when placed close and can see an inverted image when kept away. A convex mirror always forms a small and erect image.
