The angle of incidence 𝑖 is chosen such that the incident light rays will have minimum deviation if 𝑛1 = 𝑛2 = 𝑛 = 1.5. For the case of unequal refractive indices, 𝑛1 = 𝑛 and 𝑛2 = 𝑛 + Δ𝑛 (where Δ𝑛 ≪ 𝑛), the angle of emergence 𝑒 = 𝑖 + Δ𝑒. Which of the following statement(s) is(are) correct? (A) The value of Δ𝑒 (in radians) is greater than that of Δ𝑛 (B) Δ𝑒 is proportional to Δ𝑛 (C) Δ𝑒 lies between 2.0 and 3.0 milliradians, if Δ𝑛 = 2.8 × 10−3 (D) Δ𝑒 lies between 1.0 and 1.6 milliradians, if Δ𝑛 = 2.8 × 10−3
