Problem

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?
