Mathematical description of Refractive index in crystal/glass

  1. Oct 13, 2012 #1

    I have read on a website that the refractive index of glass is related to the number of electrons it has per unit volume.

    I don't recall which website it was, but is it true? & if so what is the quantitative description behind it? or is it a lot more complicated :)

    Many thanks for the replies.

    you should better take a look in feynman lectures vol.1(the origin of refractive index) and 2 both.it is not complicated if you know that an electron can be pictured as bounded to atom by a restoring force.

    These are very primitive models. Please don't extrapolate any engineering value nor deduce any comparison between glass from these models.

    Thank you very much indeed.
