I have a few straightforward questions about AC but surprisingly can't find any of explicit confirmations.

I understand that in reality all this is much more complicated but assume example below is greatly simplified case, only steady state with no any transient phenomena, TV acts like perfectly matched load without any reflections etc. For now I'm interested if my basic understanding is correct or not.


1. [Here][1] is static illustration of alternating voltage / current. And [this is][2] image from Wikipedia article about transmission line, which looks pretty similar. 

Is it animated version of AC which demonstrate propagation of alternating voltage (and current) waves from AC generator (assume it connected on left side) toward load ? 

2. Now, I plug, say, TV set power cord into electrical wall outlet. There would be exactly same picture: constantly changing electric field due charges, magnetic field (due currents) and the waves would appear between / around "live" and "neutral" conductors in the outlet as well as wires inside the cord. Is this correct ?

3. Since electric field constantly changing as I noted above, potential difference associated with the field constantly changing as well. Hence, actually, "live" and "neutral" wires (and wires inside power cord) keep permanently recharging to corresponding PD as waves propagates between them, with peaks +311V and -311V but for convenience there is famous ~220-240V RMS. 
Am I right ?

4. At same time "neutral" wire can be grounded for safety reason, so PD between "neutral" and the Earth is ~0V, right ?

5. At last I'm wonder what if we don't plug anything into outlet, will it act as open-ended transmission line ?

Sorry for my english and thanks for the help.
