Explanation
A light ray passing through a prism is refracted twice and aquires a deviation from its original direction.
: is apex angle
: is the angle between the incident angle and a line perpendicular to the surface
: is the angle between the ray leaving the prism and a line perpendicular to the surface
: is refractive index of the prism
: is dispersion of a prism
