Uses of Curved mirrors

Uses of Curved mirrors. Concave. Most technology that involves converging mirrors rely on their ability to focus the incoming light at a single point. Telescope. Light enters the telescope in parallel rays. These rays are reflected from a concave mirror to a diagonal plane mirror.
