JEE AdvancedPhysicsGeometrical OpticsMultiple correct+4 / −2
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∘\delta=60^{\circ}δ=60∘(see Figure-1). The angle of minimum deviation for red light from the same prism is δmin⁡=30∘\delta_{\min }=30^{\circ}δmin​=30∘(see Figure-2). The refractive index of the prism material for blue light is 3\sqrt{3}3​. Which of the following statement(s) is(are) correct?
