(A) The dispersive power $(\omega)$ of a prism is defined as the ratio of the angular dispersion between the extreme colors (violet and red) to the mean deviation (yellow color).Formula: $\omega = \frac{\delta_V - \delta_R}{\delta_Y}$Given:$\delta_V = 3.72^\circ$$\delta_R = 2.84^\circ$$\delta_Y = 3.28^\circ$Substituting the values:$\omega = \frac{3.72 - 2.84}{3.28}$$\omega = \frac{0.88}{3.28}$$\omega = 0.268$Thus,the dispersive power of the prism material is $0.268$.

The deviations caused in red,yellow,and violet colors for a crown glass prism are $2.84^\circ$,$3.28^\circ$,and $3.72^\circ$ respectively. The dispersive power of the prism material is:
