A radio transmitter broadcasts plane electromagnetic waves whose electric field amplitude at a particular location is V/m. What is the amplitude of the electromagnetic wave’s magnetic field at that location?
A certain 60.0-Hz ac power line radiates an electromagnetic wave having a maximum electric field strength of 13.0 kV/m.
What is the wavelength of this very-low-frequency electromagnetic wave?
What is the magnitude of the strongest magnetic field present in this wave?
During a heartbeat, a heart produces a maximum potential of 4.00 mV across a 0.300-m distance. The changing potential generates a 1.00-Hz electromagnetic wave.
What is the maximum electric field strength produced during the heartbeat?
What is the maximum magnetic field strength produced during the heartbeat?
What is the wavelength of the electromagnetic wave produced by the heartbeat?
