Why does an increased electrical permittivity reduce the phase velocity of light in a medium? Furthermore, what interactions do we see on an atomic level?
I am aware of the equation that defines the speed of light in terms of the electrical permittivity and magnetic permeability, but I do not understand their relationship.
Many thanks to anyone who is able to answer this question or/and refer me to a resource where I can obtain an answer!
