For a prism of angle θ = 60°, the refractive indices of the left and right halves are n₁ and n₂ (n₂ ≥ n₁), as shown. The incidence angle i is chosen so that the ray has minimum deviation when n₁=n₂=n=1.5. For n₁=n and n₂=n+Δn, where Δn << n, the emergence angle is e=i+Δe. Which statement(s) is/are correct?
