Question

you are given three mirror of equal size concave convex and planr how will you idemtify them without touching their surface?​

Answer 1

Explanation:

If the image formed is of same size as our face but laterally inverted for all positions, then it is a plane mirror.

If the image formed is erect and enlarged initially but gets inverted as the face is moved away, then it is a concave mirror.

If the image formed is erect and smaller in size for all positions then it is a convex mirror.

Hope it helps uh!!

Answer 2

Explanation:

We will identify the mirrors without touching as follows :

•CONVEX MIRROR :

We will identify the convex mirror by putting an object in front of it. If it will be a convex mirror then we will find that the image is always smaller than the object, doesn't matter where the object is put.

•PLAN MIRROR :

Similarly, we will identify the plan mirror by putting an object in front of it. If it will be a plan mirror then we will find that the size of image is always equal to the size the object, doesn't matter where the object is put.

•CONCAVE MIRROR :

The mirror left is the concave mirror.
