MCQ (Single Correct Answer)

-1

Two identical prisms of refractive index $$\sqrt{3}$$ are kept as shown in the figure. A light ray strikes the first prism at face AB. Find

(A) the angle of incidence so that the emergent ray from the first prism has minimum deviation;

(B) through what angle, the prism DCE should be rotated about C so that the final emergent ray also has minimum deviation?

(A) = 45$$^\circ$$, (B) = 60$$^\circ$$

(A) = 60$$^\circ$$, (B) = 45$$^\circ$$

(A) = 45$$^\circ$$, (B) = 45$$^\circ$$

(A) = 60$$^\circ$$, (B) = 60$$^\circ$$
