And we have since learned no medium is needed for light.

One form (a simplified form) is. It treats a solid dielectric as a 
homogeneous substance with a dielectric constant, rather than a huge 
collection of molecules. This works for light, but doesn't work for X-rays
with a wavelength much smaller than atoms.

You have to use the proper form.

Just not for short wave photons or when the interatomic distance is much 
larger than the wavelength.
