Concave mirrors are used in a variety of applications, including searchlights, shaving mirrors, dental mirrors, satellite dishes, and more. The collimation and concentration of light rays is a property of the concave mirrors. Concave mirrors are used as a light beam Reflector in the torches and headlights.
