Refraction of Light Through a Prism

Physics

definition

Angle of deviation

The angle of deviation through a triangular prism is defined as the angle between the incident ray and the emerging ray (angle ). It can be shown that when the angle of incidence is equal to the angle of refraction for the emerging ray, the angle of deviation is at a minimum.

Terms related to prism

Angle of prism: The angle between the two sides of the reflecting faces of prism is called angle of prism.
Angle of deviation (): Angle between the incident ray and the emergent ray is called the angle of deviation.

Description of prism

A prism is an object made up of a transparent material like glass or plastic that has at least two flat surfaces that form an acute angle (less than 90 degrees). White light is comprised of all the colors of the rainbow. When white light is passed through a prism, the colors of the rainbow emerge from the prism.
Types of prism
1. Dispersive prisms 2. Reflective prisms 3. Beam-splitting prisms 4. Polarizing prisms 5. Deflecting prisms and many more.

Definition:
The angle through which ray of light turns away from its original path on passing through a prism is called angle of deviation.
