A ray of light incident parallel to the base PQ of an isosceles right-angled triangle prism PQR suffers successive total internal reflections at the faces PQ and QR before emerging reversed in direction shown.

If the refractive index of the material of the prism is `mu`, then

Light enters an isosceles right triangular prism at normal incidence through face AB and undergoes total internal reflection at face BC as shown below. The minimum value of the refractive index of the prism is close to

A ray of ligh is incident normally on one of the faces of right angled isosceles prism as shhown above. It undergoes total internal reflection from hypotenuse. Which on of the following is the minimum refractive index of the material of the prism?

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 parallel beam of light is incident from air at an angle alpha on the side PQ of a right angled triangular prism of refractive index n=sqrt2. Light undergoes total internal reflection in the prism at the face PR when alpha has a minimum value of 45degree . The angle theta of the prism is

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

A parallel beam of light is incident from air at an angle alpha on the side PQ of a right angled triangular prism of refractive index n=sqrt2 . Light undergoes total internal reflection in the prism at the face PR when alpha has a minimum value of 45^@ . The angle theta of the prism is

A ray of light falls normally on one face of a right angled prims of refracting angle A. It suffers two total internal reflections before coming out of prism parallel to incident ray as shown. Refractive index to prism material will be:
