For a prism of prism angle theta=60 degrees, the refractive indices of the left half and the right half are respectively n1 and n2 (n2 is greater than or equal to n1) as shown in the figure. The angle of incidence i is chosen such that the incident light rays will have minimum deviation of n1=n2=n=1.5. For the case of unequal refractive indices, n1=n and n2=n+(delta)n (where (delta(n) is much, much less than n), the angle of emergence e=i+(delta)e. Which of the following statement(s) is (are) correct?
A) The value of (delta)e (in radians) is greater that of (delta)n.
B) (delta)e is proportional to (delta)n.
C) (delta)e lies between 2.0 and 3.0 milliradians if (delta)n=2.8x10^(-3).
D) (delta)e lies between 1.0 and 1.6 milliradians if (delta)n=2.8x10^(-3).
