If the refractive indices of a prism for red,yellow,and violet colours are $1.61$,$1.63$,and $1.65$ respectively,then the dispersive power of the prism will be:

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

The refractive index of a particular material is $1.67$ for blue light,$1.65$ for yellow light,and $1.63$ for red light. The dispersive power of the material is .........

The refractive index of flint glass for blue light is $1.6333$ and for red light is $1.6161$. Calculate the dispersive power of the prism,assuming the mean refractive index is approximately the average of the two given values.

Calculate the dispersive power for crown glass from the given data if $\mu_v = 1.5230$ and $\mu_r = 1.5145$.

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.
