MACROSCOPIC THEORY.
MAXWELL'S ELECTROMAGNETIC THEORY is a MACROSCOPIC theory, which means
that it treats everything, be it solid,liquid,or gas, as CONTINUOUS.
There are no atoms in "MACROSCOPIC" theory.
One could say that "NO ATOMS" is
what "MACROSCOPIC" means eh!
The "density" at every point throughout ALL SPACE,
will have a FINITE,non zero ,value,
and yet ironically
"DENSITY" does not exist
at a "POINT".
Dose it
Mr.MORONEY ?

Radio waves, light waves, and x-rays, all travel at the same speed,
Mr. Moroney, and that speed is relative to the macroscopic medium,
not the observer, Mr.Moroney.
