The source of electric waves is an increase of the voltage.

The voltage increases at the ends of a dipole.

The electric waves and sound propagate in metal wires, but with different
speeds.
Are electric waves in a wire also transversal?

yes.

" As the wave propagates along the line, it is accompanied by currents which
flow longitudinally in the conductors".

In reality no pure transversal waves. Such are only possible in the math.
