Question
A thin prism P1 with angle 6o and made from glass of refractive index 1.54 is combined with another thin prism P2 of refractive index 1.72 to produce disperision with deviation. The angle of prism P2 will be
Options
A.4o 30′
B.8.5o
C.6.5o
D.none of these
Solution
For dispersion without deviation, the necessary condition is
or, A2 =
× 6o = 4.5 ≈ 4o 30′
or, A2 =
× 6o = 4.5 ≈ 4o 30′Create a free account to view solution
