What is the equation that relates refractive index of a substance to the wavelength of light entering.? - index.of hussyfan

I remember learning, when one enters the equation, the refractive index of a substance at the wavelength of the light that. Refractive index as a function of wavelength. I have a degree in physics, but I have a vague recollection of this. Please help.
