Question:

• How will you distinguish between a plane mirror, a concave mirror and a convex mirror, without touching them?

Answer:

To distinguish between these three mirrors i.e. plane mirror, concave mirror and convex mirror, we have to hold the mirror near the face. Now, the image is obtained. There can be 3 cases.

1. If the image is upright, of same size and does not change in size by moving the mirror towards or away from the face, the mirror is a plane mirror.
2. If the image is upright and magnified and size increases on moving the mirror away then the mirror is a concave mirror.

• If the image is upright and diminished and decreases in size on moving the mirror away, then the mirror is a convex mirror.
