What should be the minimum value of refractive index of a prism, refracting angle A, so that there is no emergent ray irrespective of the angle of incidence?

The refractive index of a prism having refracting angle 75^(@) is sqrt2 . What should be the minimum angle of incidence on a refracting surface so that the ray will emerge from the other refracting surface of the prism?

The refracting angle of a prism is 60^(@) and its refractive index is sqrt((7)/(3) . What should be the minimum angle of incidence on the first refracting surface so that the ray can emerge somehow from the second refracting surface?

The refractive index of the material of a prism of refracting angle 45^@ is 1.6 for a certain monochromatic ray. What will be the minimum angle of incidence of this ray on the prism so that no TIR takes place as the ray comes out of the prism.

The refractive index of the material of a prism of refracting angle 45^@ is 1.6 for a certain monochromatic ray. What will be the minimum angle of incidence of this ray on the prism so that no TIR takes place as the ray comes out of the prism.

The refractive index of a prism is sqrt(2) and its refractive angle is 60^(@) . If a ray emerge with the minimum angle of deviation then the angle of incidence will be

A light ray is incident on one refraction face of a prism, of refractive angle A, at an angle of incidence, I and emerges from the opposite face, normally. If refractive index of the material of the prism be mu what will be the value of the angle of incidence?

A prism of refractive index sqrt(2) has refractive angle 60^(@) . Find the angle of incidence so that a ray minimum deviation.
