Refraction through a Prism

A thin prism of angle $5°$ is placed at a distance of $10 \mathrm{cm}$ from the object. The distance of the image from the object is (given $\mathrm{\mu }$ of prism$=\text{1.5}$)

A prism has a refractive index $\sqrt{\frac{3}{2}}$ and refracting angle $90°$. Find the minimum deviation produced by prism

A ray incident at angle 53^o on a prism emerges at an angle at 37^o as shown. If the angle of incidence is made 50^o, which of the following is a possible value of the angle of emergence.

A parallel beam of light falls normaly on the first face of a prism of small angle. At the second face it is partly transmitted and partly reflected, the reflected beam striking at the first face again, and emerging from it in a direction making an angle 6^o 30' with the reversed direction of the incident beam. The refracted beam is found to have undergone a deviation of 1^o 15' from the original direction. Find the refractive index of the glass and the angle of the prism.

The refractive indices of the crown glass for violet and red lights are $1.51$ and $1.49$ respectively and those of the flint glass are $1.77$ and $1.73$ respectively. A prism of angle $6°$ is made of crown glass. A beam of white light is incident at a small angle on this prism. The other thin flint glass prism is combined with the crown glass prism such that net mean deviation is $1.5°$ anticlockwise.
A screen is placed normal to the emerging beam at a distance of $2 \mathrm{m}$ from the prism combination. Find the distance between red and violet spot on the screen. Which is the topmost colour on screen.

How does the angle of minimum deviation of a glass prism vary, if the incident violet light is replaced with red light?

A given ray of light suffers minimum deviation in an equilateral prism $P$. Additional prism $Q$ and $R$ of identical shape and of the same material as $P$ are now added as shown in the figure. The ray will now suffer

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 ray coming from an object is reflected totally at the slant surface of the prism. The possible orientation of the image is
