Question

How would you differentiate between concave and convex mirrors by touching them? Answer fast

Answer 1

Answer:

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.

Answer 2

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.

so, A concave mirror gives a magnified and erect image of a nearby object whereas a convex mirror gives an erect and diminished image.
