Editing Rayleigh scattering (section)

== Effect of fluctuations ==
When the [[dielectric constant]] <math>\epsilon</math> of a certain region of volume <math>V</math> is different from the average dielectric constant of the medium <math>\bar{\epsilon}</math>, then any incident light will be scattered according to the following equation<ref>{{Cite book|title=Statistical mechanics|last=McQuarrie, Donald A.
