The dispersive power is maximum for the material

$A$ convex lens,a glass slab,a glass prism,and a solid sphere are all made of the same glass. The dispersive power will be:

Which of the following curves gives the correct graphical representation between the refractive index $\mu$ of glass and the wavelength $\lambda$ of light?

$A$ medium is said to be dispersive,if

When white light enters a prism,it gets split into its constituent colours. This is due to

Compare the dispersive powers of two prisms if one of them deviates the blue and red rays through $10^{\circ}$ and $6^{\circ}$ respectively,and the second prism through $8^{\circ}$ and $4.5^{\circ}$.
