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

The refractive index of material of prism shown in figure is

For a prism the angle of prism is equal to angle of minimum deviation and refractive index of its material is $\sqrt{3}$. Then the angle of minimum deviation will be

What is the angle of incidence for an equilateral prism of refractive index $\sqrt{3}$, so that ray is parallel to the base inside the prism?

A right-angled glass prism $(\mu =\sqrt{3})$ is kept on a horizontal surface in contact with a vertical plane mirror as shown. A ray of light travelling horizontally retraces its path when transparent liquid of refractive index $\mu$ is filled in the space between prism and mirror. Refractive index, $\mu$ of the liquid is

An equilateral triangular prism is made of glass $(\mu =1.5).$ A ray of light is incident normally on one of the faces. The angle between the incident and emergent ray is

The maximum refractive index of a prism which permits the passage of light through it, when the refracting angle of the prism is $90°,$is

For the angle of minimum deviation of a prism to be equal to its refracting angle, the prism must be made of a material whose refractive index

When a beam of white light passes through a prism it gets

A ray of light makes normal incidence on the diagonal face of a right angled prism as shown in figure . If $\mathrm{\theta }=37°,$ then the angle of deviation is $\left(\sin 37°=\frac{3}{5}\right)$

A ray of light passes through an equilateral glass prism in such a manner that the angle of incidence is equal to the angle of emergence and each of these angles is equal to ${\frac{3}{4}}^{\mathrm{th}}$ of the angle of the prism. The angle of deviation is 

Maximum deviation occurs in a homogeneous prism of refracting angle $A_1$ and having critical angle of its material as $A_2,$ when the  angle of incidence is -
