Asked by SSHHII | 16th Oct, 2009, 10:16: PM

Expert Answer:

Dispersive power is  measure of the power of a medium to separate different colors of light, equal to (n2n1)/(n - 1), where n1 and n2 are the indices of refraction at two specified widely differing wavelengths, and n is the index of refraction for the average of these wavelengths, or for the D line of sodium.
