Total reflecting prisms are :
Two isosceles right-angled glass prisms are placed near each other as shown in the following figure:
The path of the light ray entering the first isosceles right-angled glass prism till it emerges from the second identical prism is such that
A total reflecting right angled isosceles prism can be used to deviate a ray of light through :
(a) 30∘ (b) 60∘ (c) 75∘ (d) 90∘
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?
