R P Goyal and S P Tripathi Solutions for Chapter: Refraction of Light at Plane Surfaces, Exercise 2: EXERCISE-4(B)

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?

A ray of light is normally incident on one face of an equilateral glass prism. Answer the following:

What will be the angle of incidence at the second face of the prism ?
 

A ray of light is normally incident on one face of an equilateral glass prism. Answer the following:

Will the light ray suffer minimum deviation by the prism?

The figure below shows two identical prisms $A$ and $B$ placed with their faces parallel to each other. A ray of light of single colour $PQ$ is incident at the face of the prism $A$. Complete the diagram to show the path of the ray till it emerges out of the prism $B$.

In refraction of light through a prism, the light ray: 

A ray of light suffers refraction through an equilateral prism. The deviation produced by the prism does not depend on the:

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.

What should be the angle of incidence for a ray of light which suffers minimum deviation of $36°$ through an equilateral prism?
