Given, μ V=1.54, μ R=1.52, A=10o Angular dispersion (θ )=(μ V-μ R)A =(1.54-1.52)× 10o =0.2o

Q. The refractive indices of violet and red light are 1.54 and 1.52 respectively. If the angle of the prism is $10^{\circ}$ , the angular dispersion is

$0.02^{\circ}$

$0.2^{\circ}$

$3.06^{\circ}$

$30.6^{\circ}$

Given, $μ_{V} = 1.54,$ $μ_{R} = 1.52,$ $A = 10^{o}$ Angular dispersion $(θ) = (μ_{V} - μ_{R}) A$ $= (1.54 - 1.52) \times 10^{o}$ $= 0.2^{o}$

Q. The refractive indices of violet and red light are 1.54 and 1.52 respectively. If the angle of the prism is 10∘ , the angular dispersion is
