The prism angle of a prism is $10^{\circ}$. The refractive indices for red and violet colors are $1.51$ and $1.52$ respectively. The dispersive power will be .....

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

The property of light that explains the formation of coloured images due to thick lenses is

Explain the dispersion of white 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.

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 $4.5^{\circ}$.
