Q. 7

Two prisms of identical geometrical shape are combined with their refracting angles oppositely directed. The materials of the prisms have refractive indices 1.52 and 1.62 for violet light. A violet ray is deviated by 1.0° when passes symmetrically through this combination. What is the angle of the prisms?

Answer :

Given that


Refractive index of violet light through first prism =


μv1= 1.52


Refractive index of violet light from second prism =


μv2= 1.62


Deviation of violet light through prism = δ =10


Now,


Two prisms of identical geometrical shape are combined.


Let A = Angle of the prisms
