Why are concave mirrors different from convex mirrors ?

A concave mirror has an inward curved surface, like the inside of a spoon. Because of its curved shape, light rays are focused at a point in front of the mirror's surface.

Depending on where an object is placed, a concave reflecting surface can reduce and invert an image, or enlarge an image. So, if you stand in front of a concave mirror, you will notice that that the reflected image is reduced or inverted. if you move closer, your image turns over, and becomes enlarged. Concave mirrors have many uses. These include vanity mirrors that enlarge a person's face, the mirror used by dentists, and those used in reflecting telescopes.

A convex mirror has an outward bulging reflecting surface. A convex surface only reduces the size of a reflected image- it does not invert it, regardless of where an object is placed in front of it. A convex mirror allows a wider area to be seen, and its many uses include rear view mirrors in automobiles, and mirrors in stores that are used for security purposes.
