But for this you need the Electric Wave Model.
EM was stripped away by Royal Society in 1864.

Sorry to Szczepan for not answer your comments
I hard trying don't run out so much off topic :)

I am not out of topics. It is to your:
"To concentrate light we only need a piece of glass, to do the same on
HF RF region we need large wire antenna arrays. Because of this we
often need (or employ) very differents models to deal with the "same
thing". Probably Maxwell equations solve all of them, but they are
difficult ladies to deal :)."

You should read the Maxwell:
http://en.wikisource.org/wiki/On_Phy...Lines_of_Force
Maxwell described the model in English and in the math. English is not
difficult ladies to deal for you.

After this you understand why: "that Maxwell's model was stripped away and
just the equations remain".
Light and radio waves are exactly like sound.
