Question

4. How can you distinguish between plane mirror, concave and convex mirror
by merely looking at the image formed in each case?​

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.
