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". From: http://www.answers.com/topic/electro...e-transmission In reality no pure transversal waves. Such are only possible in the math. S* |
