(B) The angular dispersion produced by a prism is given by the formula: $	heta = (\mu_v - \mu_r)A$.Given:Refractive index for violet light,$\mu_v = 1.54$.Refractive index for red light,$\mu_r = 1.52$.Angle of the prism,$A = 10^{\circ}$.Substituting the values into the formula:$	heta = (1.54 - 1.52) 	imes 10^{\circ}$.$	heta = 0.02 	imes 10^{\circ}$.$	heta = 0.2^{\circ}$.Therefore,the angular dispersion is $0.2^{\circ}$.

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