Vedclass · Answer

(A) For dispersion without deviation,the net deviation produced by the combination must be zero.The condition for dispersion without deviation is given by: $(\mu - 1)A + (\mu' - 1)A' = 0$.Here,$\mu = 1.602$ (flint glass),$A = 10^{\circ}$,and $\mu' = 1.500$ (crown glass).Taking the magnitudes,we have: $(\mu - 1)A = (\mu' - 1)A'$.Substituting the values: $(1.602 - 1) 	imes 10^{\circ} = (1.500 - 1) 	imes A'$.$0.602 	imes 10^{\circ} = 0.500 	imes A'$.$A' = \frac{6.02}{0.500} = 12.04^{\circ}$.Since $0.04^{\circ} = 0.04 	imes 60' = 2.4'$,the angle $A' = 12^{\circ} 2.4'$.

$A$ flint glass prism is joined with a crown glass prism to produce dispersion without deviation. The refractive indices of these for mean rays are $1.602$ and $1.500$ respectively. If the angle of the flint glass prism is $10^{\circ}$,then the angle of the crown glass prism will be:
