Quick Answer

A convex mirror is in the shape of a curve, and the reflecting surface bulges outward toward the source of light. Because convex mirrors reflect the light in an outward direction, they do not serve to focus light.

One of the most frequent uses of a convex mirror is on the passenger side of a vehicle.

The convex shape also yields a wider field of vision.

Other places where convex mirrors appear include hallways of schools, stores, hospitals, hotels and apartment complexes where seeing around a corner is helpful These convex mirrors generally mount on the ceiling on a wall at a hallway intersection to protect against collisions. They serve to increase visibility at any intersection where it is difficult to see coming traffic. Some ATMs also have convex mirrors installed to let bank customers see what is behind them.
