A prism ABC of angle `30^(@)` has its face AC silvered. A ray of light incident at an angle of `45^(@)` at the face AB retraces its path after refraction at face AB and reflection at face AC . The refractive index of the material of the prism is

The face AC of a prism ABC of refracting angle 30^@ is silvered . A ray is incident on face AB at an angle of 45^@ as shown in figure . The refracted ray undergoes reflection at face AC and retraces its path . The refractive index of the prism is

State the conditions under which total internal reflection occurs. One face of a prism with a refracting angle of 30^(@) is coated with silver. A ray incident on another face at an angle of 45^(@) is refracted and reflected from the silver coated face and retraces its path. Find the refractive index of the material of the prism.

An isosceles prism of angle A=30^(@) has one of its surfaces silvered. Light rays falling at an angle of incidence 60^(@) on the other surface retrace their path after reflection from the silvered surface. The refractive index of prism material is

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

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.
