Total Internal Reflection and Prism

For an angle of incidence $\mathrm{\theta }$ on an equilateral prism of refractive index $\sqrt{3}$. The ray refracted is parallel to the base inside the prism. The value of $\mathrm{\theta }$ is 

The angle of minimum deviation for an incident light ray on an equilateral prism is equal to its refracting angle. The refracting index of its material is

At whole angle should a ray of light be incident on the face of a prism of refracting angle, so that it just suffers total internal reflection at the other face $\mathrm{i}$. The refracting index of the material of the prism is $1.524$.

The refractive index of the material of an equilateral prism is $\sqrt{3}$. What is the angle of minimum deviation $\delta$.

A ray of light incident on one of the faces of a glass prism of angle it has angle of incidence $2\mathrm{A}$. The refracted ray in the prism strikes the opposite face which is silvered the reflected ray from it retracing its path. Trace the ray diagram and find the relation between the refractive index of the material of the prism and the angle of prism.

Two monochromatic rays of light are incident normally on the face $\mathrm{AB}$ Of an isosceles right-angled prism $\mathrm{ABC}$. The refractive indices of the glass prism for the two rays $1 \mathrm{and} 2$ Are respectively $1.35$ and $1.45$. Trace the path of these rays after entering through the prism.

Figure shows a mixture of blue-green and red coloured rays, incident normally on a right-angled prism. The critical angles of the materials of the prism for red, green and blue are ${46}^{\mathrm{o}}$, ${44}^{\mathrm{o}}$ and ${43}^{\mathrm{o}}$ Respectively. The arrangement will separate-

Two parallel light rays are incident at one surface of a prism as shown in the figure. The prism is made of glass of refractive index $1.5$. The angle between the rays as they emerge is nearly.

A beam of light consisting of red, green and blue colours is incident on a right-angled prism. The refractive index of the material of a prism for red, green and blue wavelengths are $1:39$, $1.44$ and $1.47$ Respectively. The prism will____

A light ray is incident perpendicularly to one face of a ${90}^{\mathrm{o}}$ Prism and is totally internally reflected at the glass-air interface. If the angle of reflection is ${45}^{\mathrm{o}}$, we conclude that the refractive index $\mathrm{\mu }$.
