- The rate at which information can be transmitted on an electromagnetic wave is proportional to the frequency of the wave. Is this consistent with the fact that laser telephone transmission at visible frequencies carries far more conversations per optical fiber than conventional electronic transmission in a wire? What is the implication for ELF radio communication with submarines?If the electric field emitted by a radio tower has an amplitude of 285 V/m, what is the amplitude of the corresponding magnetic field? ____T
