A monochromatic ray of light is incident normally on one of the refracting surfaces of a prism . The emergent ray grazes the second refracting surface . What is the angle of the prism if the refractive index of the material of the prism is `1.6` ?

A ray of light is incident normally on one of the refracting surfaces of a prism of refracting angle A,. The emergent ray grazes the other refracting surface. Find the refractive index of the material ofprism.

A ray of light is incident normally on one of the refracting surfaces of prism of refracting angle 60^@ . The emergent ray grazes the other refracting surface. The refractive index of the material of the prism is

A ray LM of monochromatic light incident normally on one refracting surface AB of a regular glass prism ABC emerges in air from the adjacent surface C as shown in figure. Calculate the refractive index of the material of the prism.

A ray of light is incident normally on one face of a prism of refracting angle A. After travelling through prism, the ray emerges from the second refracting surface making an angle of deviation of delta . The refractive index of the material of prism is
