To be precise: Art wrote: "the water molecules (carriers)
move hardly at all except up and down".

Next I wrote: "They move along the eliptic trajectory. The longitudinal

So "They" The water molecules not "Electrons"

It is very important to know that the water waves are not transversal.
Everybody who know that understand that in reality no pure transversal
waves. In reality are waves which interfere.

The electrons are NOT the EM photonic waves. The electrons
are the carriers for the EM photonic waves. It is NOT the
electrons that have the transversal wave characteristics.
The movement of the electrons in the conductor is indeed
longitudinal but that movement is close to infinitesimally
small at RF frequencies. The movement is more like an
oscillation in place.

I do not know what are movements of elecrtons in conductor but in air
(lightning) they oscillate with RF frequences and that movement is not close
to infinitesimally small (kilometers).
