Refractive index for a material for infrared light is

A thin prism produces an angular dispersion of 24. If the refracting angle of the prism is 3^(@) , and the refractive index of the material of the prism for red colour is 1.55 . What is the refractive index of its material for violet light ?

Light enters at an angle of incidence in a transparent rod of refractive index n. For what value of the refractive index of the material of the rod the light once entered into it will not leave it through its lateral face whatsoever be the value of angle of incidence.

Predict how the velocity of light is changed when it travels from a material with higher refractive index to a material with lower refractive index.

How is the refractive index of a material related to the speed of light in it?

The refractive index of a material is sqrt3 . What is the angle of refraction if the unpolarised light is incident on it at the polarising angle of the medium.
