What Is the Definition of a Convex Mirror?
A convex mirror performs the same reflective use as a regular flat mirror, except the convex mirror is a spherical reflecting surface. It bows outward, like the exterior of a ball, as opposed to a concave mirror, which bows inward.FunctionConvex mirrors reflect parallel light rays outward to the sides in all directions. They will also take in light from all directions. These rays are diverged into a central focal point that makes the image appear as though it’s behind the mirror.BenefitsConvex mirrors offer a wider view than traditional flat mirrors.UsesConvex mirrors are used as car rear-view mirrors, as department store security mirror and as reflectors in street lamps, flashlights and telescopes.ConsiderationsObjects in a concave mirror are diminished in size. This is the reason for the warning label on rear-view mirrors that state objects may be closer than they appear.FactA convex mirror’s image is actually a virtual image, meaning it cannot be projected on a screen.
