A mirror is an object that reflects light or sound in a way that preserves much of its original quality subsequent to its contact with the mirror. Some mirrors also filter out some wavelengths, while preserving other wavelengths in the reflection. This is different from other light-reflecting objects that do not preserve much of the original wave signal other than color and diffuse reflected light. The most familiar type of mirror is the plane mirror, which has a flat surface. Curved mirrors are also used, to produce magnified or diminished images or focus light or simply distort the reflected image.
Mirrors are commonly used for personal grooming or admiring oneself (in which case the archaic term looking-glass is sometimes still used), decoration, and architecture. Mirrors are also used in scientific apparatus such as telescopes and lasers, cameras, and industrial machinery. Most mirrors are designed for visible light; however, mirrors designed for other types of waves or other wavelengths of electromagnetic radiation are also used, especially in non-optical instruments.

Famous quotes containing the word mirror:
“A novel is a mirror carried along a high road. At one moment it reflects to your vision the azure skies at another the mire of the puddles at your feet. And the man who carries this mirror in his pack will be accused by you of being immoral! His mirror shews [sic] the mire, and you blame the mirror! Rather blame that high road upon which the puddle lies, still more the inspector of roads who allows the water to gather and the puddle to form.”
—Stendhal [Marie Henri Beyle] (1783–1842)
“She left the web, she left the loom,
She made three paces through the room,
She saw the water-lily bloom,
She saw the helmet and the plume,
She looked down to Camelot.
Out flew the web and floated wide;
The mirror cracked from side to side;
“The curse is come upon me,” cried
The Lady of Shalott.”
—Alfred Tennyson (1809–1892)
“Women ... are completely alone, though they were born and bred upon this soil, as if they belonged to another class in creation.”
—“Jennie June” Croly 1829–1901, U.S. founder of the woman’s club movement, journalist, author, editor. F, Demorest’s Illustrated Monthly Mirror of Fashions, pp. 363-4 (December 1870)
