For a material,the refractive indices for red,violet,and yellow color light are respectively $1.52, 1.64,$ and $1.60.$ The dispersive power of the material is:

The focal lengths of a convex lens for red and blue light are $100 \text{ cm}$ and $96.8 \text{ cm}$ respectively. The dispersive power of the material of the lens is:

If the refractive indices of crown glass for red,yellow,and violet colours are $1.5140, 1.5170$,and $1.5318$ respectively,and for flint glass these are $1.6434, 1.6499$,and $1.6852$ respectively,then the dispersive powers for crown and flint glass are respectively:

Mention the constituent colors of white light.

The splitting of white light into several colours on passing through a glass prism is due to

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