At what angle should a ray of light be incident on the face of a prism of refracting angle `60^(@)` so that it just suffers total internal reflection at the other face ? The refractive index of the prism is 1.524.

A ray of light is incident on a glass prism of refractive index mu and refractive angle A. If it just suffers total internal reflection at the other face, obtain an expression relating the angle of incidence , angle of prism and critical angle.

A drop of liquid is spread over the hypotenuse of a right angled isosceles prism as shown in Fig. and a ray of light is incident normally on face AB of the prism. If refractive index of liquid is sqrt(2) , then for total internal reflection to occur, refractive index of material prism should be :

Calculate the angle of incidence on the face of a prism of refracting angle 60^(@) and of refractive index 1.5, for which the emergent ray just grazes the other face.

A ray of light is incident at 65^(@) on one face of a prism of angle of 30^(@) and the emergent ray makes 35^(@) with the incident ray. The refractive index of the prism is:

A ray of light is incident at 60^(@) on one face of a prism of angle 30^(@) and the emergent ray makes 30^(@) with the incident ray. The refractive index of the prism is

A ray of monochromatic light is incident on one refracting face of a prism of refracting angle 75^(@) . It passes through the prism and is incident on the other face at the critical angle If the refracive index of the material of prism is sqrt(2) , the angle of incidence on the first face o the prism is

A ray of monochromatic light is incident on the refracting face of a prism (angle 75^(@)0 . It passes through the prism and is incident on the other face at the critical angle. If the refractive index of the prism is sqrt(2) , then the angle of incidence on the first of the prism is
