Question

If you are given a plane mirror, a concave mirror, and a convex mirror, how will you distinguish between them by touching their surface?​

Answer 1

Answer:

As we know that in a concave mirror the size of the image formed is enlarged w.r.t. the real image. And in the convex mirror the size of the image formed is diminished w.r.t. the real image. This is the basic difference by which we can distinguish between concave and convex mirrors without touching them.
