What causes the phenomenon of dispersion?

Asked by Topperlearning User | 4th Jun, 2014, 01:23: PM

Expert Answer:

There is dispersion because each colour has its own characteristic wavelength ().
From Cauchy’s Formula we know that the refractive index of a material depends on wavelength of light.
