I never said the amplifier created the audio signal. OK wave not pulse, pulse would be digital. The point I was making is an " audio signal" in wire is an electrical description of that signal and it travels in the wire mostly the outer third though all of the wire carries it especially if the speaker wire is no more than 1/2 inch thick.
Simple question, or is it...
What exactly is an audio signal made of, and what exactly is the medium it travels through in a cable??

The signal is not the Poynting vectors. The direction of the Poynting vectors are not even in the direction of the current. You know what a vector is, right? We’ve already covered all that. Come on, guys. Wake up and smell the coffee! ☕️ Stop trying to cherry pick 🍒 Wikipedia. Photons have no problem traveling through solid material like say, glass and water. That’s pretty obvious. Especially for high energy photons. |
Electrical energy delivered to the load is flowing entirely through the dielectric between the conductors. Very little energy flows in the conductors themselves, Stay on point..... |
