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 material of the prism is 1.524.

A thin prism of 2^@ angle gives a deviation of 1^@ . What is the value of refractive index of the material of the prism?

A thin prism of 20^@ angle gives a deviation of 1^@ . What is the value of refractive index of the material of the prism?

A thin prism of 5^@ angle gives a deviation of 3.2^@ .What is the value of refractive index of teh material of the prism?

A ray of light is incident on the surface of a glass plate of refractive index 1.536 at the polarising angle.Calculate the angle of refraction.

A ray of light is incident normally on one of the faces of a prism of apex angle 30^@ and refractive index sqrt2 .Find the angle of deviation for the ray of light.

A ray of light incident at 49^@ on the face of an equilateral prism passes symmetrically.Calculate thr efractive index of the material of the prism.

A ray of light is incident at an angle of 60^@ on the first face of a prism of an angle 30^@ .The ray emergingn out of the prism makes an angle of 30^@ with the incident ray as shown in Fig.3.13. . calculate the refractive index of the material of the prism.

A ray is incident at an angle of incidence i on one surface of a prism of small angle A and emerges normally from the opposite surface. If the refractive index of the material of the prism is mu , the angle of incidence i is nearly equal to

A ray of light incident on the horizontal surface of a glass slab t 70^@ just grazes the adjacent vertical surface after refraction. Compute the critical angle and refractive index of the glass.
