For a prism of prism angle $$\theta = 60^\circ$$, the refractive indices of the left half and the right half are, respectively, $$n_1$$ and $$n_2 (n_2 \geq n_1)$$ as shown in the figure. The angle of incidence 𝑖 is chosen such that the incident light rays will have minimum deviation if $$n_1 = n_2 = n = 1.5$$. For the case of unequal refractive indices, $$n_1 = n$$ and $$n_2 = n + \triangle n$$ (where $$\triangle n \ll n$$), the angle of emergence $$e = i + \triangle e$$. Which of the following statement(s) is(are) correct?
