Question

Three mirors one plane one concave and one convex are lying on the table how can person identify them without touching them or using any other appartaus or device

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.
