Question:

In the United States, the ac household current oscillates at a frequency of 60 Hz. In the time it takes for the current to make one oscillation, how far has the electromagnetic wave traveled from the current carrying wire? This distance is the wavelength of a 60-Hz EM wave. Compare this length with the distance from Boston to Los Angeles (4200 km).
