Curved,
or spherical, mirrors are also known as concave and convex mirrors.
Calculations about the images formed by these lenses are based on the
assumption that the curved section of the mirror was sliced off of a
sphere. Concave mirrors are mirrors that curve inward in the middle,
forming a cave-like hollow in the center of the mirror. Convex
mirrors are mirrors that curve outward in the middle, forming a
bubble-like curvature at the center of the mirror. There are many
uses for concave and convex mirrors, mostly in the areas of science
and safety.

mirrors are used in vehicle headlights to focus the light from the
headlight. The light is not as diffused and the driver can see
better at night.
