AM Radio waves are mostly ground waves. Electric waves through air have short legs, as Tesla discovered. Electric waves are longitudinal, as Tesla discovered. It seems like an exact match. Although it is an illusion that longitudinal waves travel faster than c because the tester needs to be certain the waves are not taking a shortcut. That's why the Borderlands coil experiment showed the illusion of faster than c, because the coil wire was not in a straight line so that it could take shortcuts between windings.

Is there a way to show longitudinal like we did with sound when we were klids?

clear plastic tube with cork sprinkled in the bottom of it and a speaker on one end playing a tone, you can see the wave as it looks like a sine wave and you can see the frequency at the zero points
