 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.

  1. Convex Mirror Uses Inside Buildings
