Question

How to distinguish between a plane mirror, a concave mirror and a convex mirror witout

touching them?​

Answer 1

Answer:

: 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.

If the image is upright of the same size as the object and it does not change

in size by moving the object the mirror is plane.

If the image is upright magnified and it becomes inverted on moving the

object away from the mirror then the mirror is concave.

If the image is upright and diminished and it remains upright on moving

the object away from the mirror then the mirror is convex.
