The refractive indices of a material for red, violet and yellow colour lights are 1.52, 1.62 and 1.59 respectively. Calculate the dispersive power of the material. If the mean deviation is 40^@ what will be the angular dispersion produced by a prism of this material ?

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

For a medium, refractive indices for violet, red and yellow are 1.62, 1.52 and 1.55 respectively, then dispersive power of medium will be

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