Question
A thin prism P1 with angle 4o and made from glass of refrective index 1.54 is combined with another this prism P2 made from glass of refrective index 1.72 to produce dispersion without deviation. The angle of the prism P2 is
Options
A.5.33o
B.4o
C.3o
D.2.6o
Solution
Deviation δ = (μ - 1)A
Given δnet = 0
∴ (μ1 - 1) A1 = (μ2 - 1) A2
or A2 =
(4o) = 3o
Given δnet = 0
∴ (μ1 - 1) A1 = (μ2 - 1) A2
or A2 =
(4o) = 3oCreate a free account to view solution
