For a prism angle `theta = 60^0` the refractive indices of the left half and right half are resp, n1 and n2 (n2gen1) as shown in figure. The angle of incidence i is chosen such that the incident light rays will have minimum deviation if n1 = n2 = n = 1.5. For case of unequal refractive indices n1 = n and `n2 = n+ delat(n)` the angle of emergence `e = i + delta (e)`. Which of the following statement is/are correct?

Options

A. value of `delta(e)` (in radians) is greater than that of `delta(n)`
B. value of `delta(e)` (in radians) is propotional `delta(n)`
C. `delta(e)` lies between 2.0 and 3.0 milliradians `delta(n) = 2.8 x 10^-3`
D. `delta(e)` lies between 1.0 and 1.6 milliradians `delta(n) = 2.8 x 10^-3`
