What is a prism?
user
A prism is a geometric solid with straight sides that taper to a point at each end. It is constructed from three or more equilateral triangles, hexagons, or squares that form its sides and its faces are usually polygons but may be rounded or angled. Prisms have many uses such as in optical instruments, as glass vessels, telescopes, and in architecture for lanterns, vases, and columns.

A prism is a transparent optical element made from two or more pieces of crystal or glass which causes light to refract as it passes through the material. The shape of a prism usually determines its ability to split up (disperse) white light into the colors of the rainbow (chromatic dispersion). Prisms are also used in lighthouses, spectrometers and solar telescopes, among other applications.
