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?

Question

Philoid · Accepted Answer

Given that

Refractive index of violet light through first prism =

μ_v1= 1.52

Refractive index of violet light from second prism =

μ_v2= 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
