The primary purpose of a mirror is to reflect light, enabling the viewer to see a reflection of themselves or their surroundings. Mirrors are made of glass or a reflective material coated with a thin layer of metal, commonly silver or aluminum. Their ability to produce a clear, undistorted image allows them to be used in a variety of applications, from personal grooming to architectural design. Beyond their basic function, mirrors can also create illusions of space in smaller rooms, enhance lighting by reflecting light sources, and are utilized in optical instruments. The design and placement of mirrors significantly influence aesthetics and functionality.
