A point source of light is kept on the surface of a sphere and it is found that parallel light rays emerge from the other side of the sphere. What is refractive index of material of the sphere ?

A ray of light falls on a transparent sphere with center at C as shown in Figure . The ray emerges fromk the sphere paralllel to line AB. Find the refractive index of the sphere.

Parallel rays are incident on a transparent sphere along its one diameter. After refraction, these rays converge at the other end of this diameter. The refractive index for the material of sphere is

A ray of light falls on a transparent sphere with centre at C as shown in figure. The ray emerges from the sphere parallel to line AB. The refractive index of the sphere is

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 prism of refracting angle 60^@ . The emergent ray grazes the other refracting surface. The refractive index of the material of the prism is

The angles of refraction of a very thin prism is 1^(@) . A light say is incident normally on one of the refracting surface. The ray that ultimately emerges from the first surface, after suffering from the second surface. Makes an angle of 3.32^(@) with the normal. the deviation of the ray emerging from the second surface and the refractive index of the material of the prism respectivley, are
