Refraction Through a Prism

A glass prism of absolute refractive index of $1.52$ is surrounded by a medium. The emergent rays are bent either upwards or downwards.

Select the suitable surrounding mediums from the given table of refractive indices here for each of the above refractions through the prisms P and Q. Give reason for the choice of the mediums.

In the given combination of three triangular prisms, a ray of light enters the first prism on the left and exits from prism on the right after refraction. Consider the angles of the prisms to be small and the ratio $A_0/A=2$.

Prove that for a net deviation produced in the light ray to be zero, $\mu ={\mu }_0$ in the given combination.

The angle of minimum deviation for a glass prism with $\mu =\sqrt{3}$ equals the refracting angle of the prism. What is the angle of the prism?

A beam of light consisting of three colours namely red (R), Green (G) and yellow (Y) is incident on the prism as shown below. Complete the diagram to show refracted and emergent ray.

What is the relation between $\mathrm{i}$ and $\mathrm{e}$ when a prism is in the position of minimum deviation? 

A ray passes through an equilateral glass prism such that $\mathrm{i}=\mathrm{e},$ which is $3/4$ of the prism angle. Then deviation will be -

Read the paragraph and the figure carefully and answer the questions.

The figure shows a constant deviation prism $ABCD.$ The incident ray is $PQ$ and the emergent ray is $ST.$ Although it is made up of one piece of glass, it is equivalent to two $30°-60°-90°$ prisms and one $45°-45-90°$ prism. The angle ${\theta }_1$ is the angle of incidence on face $AB$. The path of the ray inside the prism is indicated in the figure. For this prism, $\mu =2\sin {\theta }_1$

The graph is plotted between the angle of deviation $\left(\delta \right)$ and angle of incidence $\left(i\right)$ for a triangular prism is represented by which of the following:
