What is a prism?
user
A prism is an optical element that distributes light over a surface, forming a spectrum of colors. It is composed of two types of elements: the incident surface, which controls the amount and direction of light entering the prism; and the dispersing surface, which separates incoming light into its component colors. The amount and dispersion of color produced by a prism depends on its angle and material composition.

A prism is an optical instrument with flat, polished sides that are used to spread orrefract light. It takes a single source of light and disperses it into its component colors, creating a beautiful display of rainbow hues.
