For a ray of light refracted through a prism of angle 60^(@) , the angle of incidence is equal to the angle of emergence, each equal to 45^(@) . Find the refractive index of the material of the prism.

For a ray of light refracted through a prism of angle 60^(@) , the angle of incidence is equal to the angle of emergence, each equal to 45^(@) . Find the refractive index of the material of the prism.

The refiracting angle of a prism is A and the refractive index of the material of the prism is cot(A/2) . The angle of minimum deviation of the prism is .

A ray of light is incident at an angle of incidence 45^@ on an equilateral prism and emerge at an angle 45^@ then the refractive index of the medium of the prism is:

The light ray is incidence at angle of 60^(@) on a prism of angle 45^(@) . When the light ray falls on the other surface at 90^(@) , the refractive index of the material of prism mu and the angle of deviation delta are given by

A ray is incident at an angle of incidence i on one surface of a small angle prism (with angle of prism A) and emerges normally from the opposite surface. If the refractive index of the material of the prism is mu , then the angle of incidence is nearly equal to:

The angle of minimum deviation caused by a prism is equal to the angle of the prism. What are the possible values of refractive index of the material of the prism?
