A thin prism P1 with angle 4o4o and made from glass of refractive index is 1.54 is combined with another thin prism P2 made from glass of refractive index 1.72 to produce dispersion without deviation. The angle of the prism P2 is: 1) 5.33o 2) 3o 3) 4o 4) 2.6o
Net deviation is zero.
Deviation by prism A=A=deviation by prism BB
A1(μ1−1) = A2(μ2−1)
4(1.54−1) = A2(1.72 − 1)
A2 = 3?
