Refraction Through a 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.

The angle of _____ increases with the increase in the angle of prism.

The angle of deviation depends on the refractive index of the glass.

A certain thin prism is found to produce a minimum deviation of ${40}^{\mathrm{o}}$ and produces a deviation of $44º$ when the angle of incidence is either ${42}^{\mathrm{o}}$ or ${62}^{\mathrm{o}}$. The angle of incidence when light undergoes minimum deviation in degree is,
