The sides of an isosceles right prism are coated with a reflecting coating. A ray of light falls on the hypotenuse at an arbitrary angle i. For what value of i the ray leaving the prism is parallel to the incident ray ?

A ray of light PQ is incident normally on the hypotenuse of a right angled prism ABC as shown in the diagram given below: What is the value of the angle of deviation of the ray ?

A ray of light PQ is incident normally on the hypotenuse of a right angled prism ABC as shown in the diagram. Name an instrument where this action of the prism is used.

A total reflecting right angled isosceles prism can be used to deviate a ray of light through :

A ray of light falls on a right angled prism ABC (AB=BC) and travels as shown in figure. What is the refractive index of material of the prism ?

Light of wavelength 5000Å falls on a plane reflecting surface. What are the wavelength and frequency of reflected light ? For what angle of incidence is the reflected ray normal to the incident ray ?

An isosceles prism has one of the refracting surfaces silvered. A ray of light is incident normally on the refracting face AB. After two reflections, the ray emerges from the base of the prism perpendicular to it. Find the angle of the prism.

In figure, a ray of light PQ is incident normally on the hypotenuse of an isosceles right angled prism ABC. (a) complete the path of the ray PQ till it emerges from the prism. Mark in the diagram the angle wherever necessary. (b) what is the angle of deviation of the ray PQ ? (c) Name a device in which this action is used.

A ray of light falls on a normally on a refracting face of a prism. Find the angle of prism if the ray just fails to emerge from the prism (mu=3//2).

(a) Figure shows two isosceles right angled prisms A and B and the light rays incident on the prism A. complete the diagram to show the rays emerging out of the prism B. (b) State the principle used for completing the ray diagram in part (a) above.

What is the angle of incidence for an equilateral prism of refractive index sqrt(3) so that the ray si parallel to the base inside the prism?
