A ray of light incident normally on one of the faces of a right-angle isosceles prism is found to be totally reflected as shown in the figure. What is the minimum value of the refractive index of the material of the prism? When the prism is immersed in water, trace the path of the emergent ray for the same incident ray, indicating the values of all the angles (mu_omega=4//3) .

A ray of light is incident normally on one face of a right-angled isosceles prism and then it grazes the hypotenuse. The refractive index of the material of the prism is

The refractive angle of prism is A. A ray is incident normally on one of the refracting faces of a prism and emerges out. If D be the deviation of the ray then refractive index of the material of the prism is—

A ray of light is incident on the hypotenuse of a right-angled prism after travelling parallel to the base inside the prism. If mu is the refractive index of the material of the prism, the maximum value of the base angle for which light is totally reflected from the hypotenuse is
