Question
A ray of light is normally incident on one face of an equilateral glass prism. Answer the following:
What is the angle of refraction from the first face of the prism?
Solution
The incident beam passes through a glass prism without deviating, and the angle that the refracted ray makes with the normal is known as the Angle of Refraction. This is zero (0°) in this instance.

A ray of light incident at an angle of incidence 48° on a prism of refracting angle 60° suffers minimum deviation. Calculate the angle of minimum deviation.
[Hint: δmin = 2i - A]
What should be the angle of incidence for a ray of light which suffers a minimum deviation of 36° through an equilateral prism?
[Hint: A = 60°, i = (A + δmin)/2]
Assertion: The light emerges from a parallel-sided glass slab in a direction perpendicular to that in which enters the glass slab.
Reason: The perpendicular distance between the original path of the incident ray and the emergent ray coming out of the glass slab is called lateral displacement of the emergent ray of light.
