What is a prism?
<|assistant|>
A prism is a transparent optical element that separates light into its component frequencies. A regular geometric shape (e.g. a triangle, square, etc.) that refracts light is called a refracting shape, and a prism is a special kind of refracting shape. 
In addition, a prism can be used as an optical instrument to study the dispersion of light and analyze its components. It is also used for color mixing, beam division, and as a component of various optoelectronic devices.
