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

What is a dispersive medium?

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

The refractive indices of red,yellow,and violet colors for a prism are $1.5140, 1.5170$,and $1.5318$ respectively. Calculate the dispersive power of this prism. For a second prism,the refractive indices for red,yellow,and violet colors are $1.6434, 1.6499$,and $1.6852$ respectively. Calculate the dispersive power of the second prism.

In the phenomenon of dispersion without deviation,which of the following statements is true?

The dispersion for a medium of wavelength $\lambda$ is $D$. Then,the dispersion for the wavelength $2\lambda$ will be:
