Question

Explain and define dispersive power of a transparent material.Obtain its expressions in terms of angles of deviation and refractive indices.


Please give right answer​

Answer 1

Answer:

Definition of dispersive power. : the power of a transparent medium to separate different colors of light by refraction as measured by the difference in refractivity for two specified widely differing wavelengths divided by the refractivity at some specified intermediate wavelength.

Answer 2

$Answer$

The power of a transparent medium to separate different colors of light by refraction as measured by the difference in refractivity for two specified widely differing wavelengths divided by the refractivity at some specified intermediate wavelength.
