Question
The figure shows a combination of two thin prism producing dispersion without deviation (μ1 = 1.54, μ2 = 1.72).
The value of θis
The value of θis
Options
A.1o
B.2o
C.3o
D.4o
Solution
For zero deviation (μ1 - 1)A1 - (μ2 - 1)A2 = 0
⇒ (1.54 - 1)4 = (1.72 - 1)θ
θ = 3o
⇒ (1.54 - 1)4 = (1.72 - 1)θ
θ = 3o
