What's the use of mirrors?

Flat mirrors are often used by people to decorate their own appearance, while curved mirrors are mainly used as dressing mirrors, furniture accessories, architectural decoration parts, optical instruments, solar cookers, reflectors for headlights and searchlights, reflecting telescope, car rearview mirrors, etc.

In science, mirrors are also commonly used in telescopes, lasers, industrial instruments and other instruments. Metal devices with regular reflective surfaces and glass or metal products with metal reflective films are often inlaid with metal, plastic or wooden frames.

Whether it is a flat mirror or a non-flat mirror, light will obey the law of reflection and be reflected by the flat mirror, and the reflected light can form vision in the retina after entering the eye. On a flat mirror, a parallel beam hits the mirror, and the whole body changes direction in a parallel way. At this time, the imaging is the same as what the eyes see.
