AIPMT 2004 | Geometrical Optics Question 67 | Physics

The refractive index of the material of a prism is $$\sqrt 2 $$ and its refracting angle is 30^o. One of the refracting surfaces of the prism is made a mirror inwards. A beam of monochromatic light entering the prism from the other face with retrace its path after reflection from the mirrored surface if its angle of incidence on the prism is

45^o

60^o

30^o

$$f' = f,f'' = 2f$$

$$f' = 2f,f'' = f$$

$$f' = f,f'' = f$$

$$f' = 2f,f'' = 2f$$
