Measure the Angle of Deviation of a Prism

A prism is a transparent medium bounded by two plane surfaces inclined to each other at a suitable angle. The angle between two surfaces is known as refracting angle or angle of prism. In a prism, a ray of light suffers two refraction and the result is deviation. In other words, we say that after passing through prism the ray of light deviates through a certain angle from its original path.
