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 ray of light is incident at an angle of 60^@ on one face of a prism which has an angle of 30^@ . The ray emerging out of the prism makes an angle of 30^@ with the incident ray. The refractive index of the material of the prism is

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

A ray of light is incident normally on one of the faces of a prism of angle 30^@ and refractive index sqrt 2 . The angle of deviation of the ray is

A parallel beam of light is incident on a face of a prism of refracting angle 60^@ . Find the refractive index of the prism if the angle of minimum deviation is 40. What is the new angle of minimum deviation if the prism is immersed in water of refractive index 1.33?

Light is incident on a glass plate at an angle of 60^@ . The reflected and refracted rays are mutually perpendicular to each other. The refractive index of the plate is

A prism is made of glass of unknown refractive index. A parallel beam of light is incident on a face of the prism. The angle of minimum deviation is measured to be 40^(@) . What is the refractive index of the material of the prism? The refracting angle of the prism is 60^(@) . If the prism is placed in water (refractive index 1.33), predict the new angle of minimum deviation of a parallel beam of light
