(B) The dispersive power $\omega$ of a prism is defined as the ratio of the angular dispersion to the mean deviation produced by the prism.Mathematically,$\omega = \frac{\mu_v - \mu_r}{\mu - 1}$,where $\mu_v$ and $\mu_r$ are the refractive indices for violet and red light,and $\mu$ is the mean refractive index.Since $\mu_v, \mu_r,$ and $\mu$ are properties of the material of the prism,the dispersive power $\omega$ depends only on the nature of the material of the prism and is independent of the prism's angle or shape.
