Refraction of Light through a Prism
Refraction of Light through a Prism: Overview
A prism is a transparent material bounded by two triangular and three rectangular lateral surfaces. The rectangular surfaces are inclined to each other. The shape of a prism makes the refracted ray deviate from the direction of the incident ray.
