A plane polarized blue light ray is incident on a prism such that there is no reflection from the surface of the prism. The angle of deviation of the emergent ray is δ = 60° (see Figure-1). The angle of minimum deviation for red light from the same prism is δmin = 30° (see Figure - 2). The refractive index of the prism material for blue light is √3. Which of the following statement(s) is(are) correct?

Derived solution: Step 1: For a prism use r₁ + r₂ = A and δ = i + e - A. At minimum deviation i = e and r₁ = r₂ = A/2, so μ = sin[(A + δₘ)/2]/sin(A/2). Step 2: Test each statement independently using these relations and the data/figure. Step 3: The statements that satisfy the required optical conditions are A: The blue light is polarized in the plane of incidence.; C: The refractive index of the material of the prism for red light is √2.; D: The angle of refraction for blue light in air at the…
