A mirror is an object whose surface has good specular reflection; that is, it is smooth sufficient to form an image. The most common type of mirror is the plane mirror, which has a flat surface. Curved mirrors are also used, to produce magnified or demagnified images or focus light.
The most common use of mirrors is for personal hygiene. However, mirrors are also used in scientific apparatus such as telescopes and lasers, as well as industrial machinery. Most mirrors are designed for visible light, however, mirrors intended for other wavelengths of electromagnetic radiation are also used, particularly in optical instruments.
