I am not sure I understand the difference between EM wave propogation and
electrical signals propagation velocity. Isn't EM waves and electrical
signals the exact same thing?
Of course whether or not it is a wave largely depends on the
frequency/wavelength one considers or "cares about".
I guess I don't follow your distinction. It is interesting so I wonder if
you could clarify.
