Question1. A U.S. or Canadian broadcasting licence for a (large) FM radio station stipulates a maximum broadcast power of 100 kW. At any distance from the broadcast antenna the intensity doesn’t quite follow the inverse square law that is described for spherical waves in the videos lectures, because of reflection of the signal off of the ground. But the inverse square law is not a bad approximation, so let’s use it a) Find the intensity of the radio signal from...

[8] An FM broadcasting station has a power of 200,000 Watts. A portable FM radio is capable of detecting FM waves with an energy density as weak as Utot = 1 x 10-14 J/m3. Recalling that intensity, S, is power/area, estimate the maximum distance (in km) the radio can be from the broadcasting station. Recall that area is the spherical area: A = 4772 Show all work
