Question

can someone explain me the prism theory of Ray optics please urgent!!!!!

Answer 1

In optics, a prism is a transparent optical element with flat, polished surfaces that refractlight. At least two of the flat surfaces must have an angle between them. The exact angles between the surfaces depend on the application. The traditional geometrical shape is that of a triangular prism with a triangular base and rectangular sides, and in colloquial use "prism" usually refers to this type. Some types of optical prism are not in fact in the shape of geometric prisms. Prisms can be made from any material that is transparent to thewavelengths for which they are designed. Typical materials includeglass, plastic, and fluorite.

A dispersive prism can be used to break light up into its constituentspectral colors (the colors of therainbow). Furthermore, prisms can be used to reflect light, or to split light into components with differentpolarizations.
