For this reason, waves in water travel at the speed of sound, but waves in a sea of charge will travel much faster as the forces from one electron are applied to many distant electrons and not to only the neighbors in direct contact.
Zbog ovoga talasi u vodi putuju brzinom zvuka ali talasi u moru elektriciteta će putovati mnogo brže pošto sile jednog elektrona utiču na mnoge udaljene elektrone a ne samo na susedne sa kojima su u direktnom kontaktu.
