FM radio station KRTH in Los Angeles broadcasts on an assigned frequency of 101 MHz with a power of 50,000 W.
(a) What is the wavelength of the radio waves produced by this
station?
(b) Estimate the average intensity of the wave at a distance of
35.3 km from the radio transmitting antenna. Assume for the purpose
of this estimate that the antenna radiates equally in all
directions, so that the intensity is constant over a hemisphere
centered on the antenna.
(c) Estimate the amplitude of the electric field at this
distance.
