Consider two isosceles prisms 1 and 2 with prism angles A₁ and A₂ and refractive indices n₁ and n₂, respectively, as shown in the figure. The faces a₁b₁ and a₂b₂ are parallel to each other and perpendicular to the mirror M. If a ray of light is incident on the face a₁c₁ and emerges from the face a₂c₂, then the correct statement(s) is/are:

Select all that apply

• Option A

  If both the prisms are at minimum deviation condition, then n₂/n₁ = sin(A₁/2)/sin(A₂/2).

• Option B

  If prism 2 is at minimum deviation condition, then sin i₁ = n₂ sin(A₂/2) is always true.

• Option C

  If both prisms 1 and 2 are thin and are at minimum deviation condition with angles of deviation δ(min,1) and δ(min,2), respectively, then θ = δ(min,1)/[2(n₁-1)] + δ(min,2)/[2(n₂-1)].

• Option D

  If prism 1 is at minimum deviation condition, then sin i₂ = n₁ sin(A₁/2) is always true.
