Vibration - a Foundation of Creation
Quoting: Sickscent quite imprecise
different physical things have wildly different vibrational modes
it's not always just a simple back and forth
some of the most important to what you're inadequately trying to say here are rotational vibrational modes
especially those creating torsion fields as a result
The reflected wave will superimpose upon the incident waves doubling the amplitude.
Quoting: Sickscent but only if it's in phase
if it's out of phase it will cancel out the incident wave with the result being NO wave (phase conjugation)
Do that with RF however ,considering the above first vibrational point you made and you get a whole different animal
and that's where the fun begins FOR REAL
on top of all that the 'wave' you're talking about is a transverse wave not a longitudinal wave
that's only a special case and an effect only anyway.
also largely ignoring the poynting vector...
did you want to talk about vibration or are you just making small talk ?
