What is used to separate white light into its various colors?

 

Solution:

Concept: A prism is a transparent optical component that refracts light and has flat, polished surfaces in optics. There must be an angle between at least two of the flat surfaces. 

The application determines the precise angles between the surfaces. The term "prism" is typically used to refer to a triangular prism, which has a triangular base and rectangular sides. 

This shape is the traditional geometrical shape. Light can be split into its individual spectral colors using a prism (the colors of the rainbow). 

Additionally, prisms can be used to split light into components with various polarizations or to reflect light. Instead of for dispersion, prisms are occasionally used for internal reflection at surfaces.
