An AM radio station broadcasts with a wavelength of 484 m. Its transmitting antenna is vertical, resulting in vertically polarized radio waves (i.e, the electric field of the waves is vertical). You observe the station's signal at a point where it's propagating due east, and where the amplitude of the wave's electric field is 347 mV/m. Find (a) the wave frequency, (b) the amplitude of the wave's magnetic field, and (c) the direction of the magnetic field.

The number associated with a radio station is the _______ of the radio waves being transmitted.amplitudemagnitudeintensityfrequency
