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...

[Ipt] A radio station operating at 100.7 MIz broadcasts from two identical antennae at the same elevation but separated by a 8.49 m horizontal distance d, as seen in the figure below Antenna 1 Midline_-L.- Antenna 2 A maximum signal is found along the midline, perpendicular to d at its midpoint and extending horizontally in both directions. If the midline is taken as 0, what is the smallest angle theta where a maximum signal is detected? Assume all measurements are...

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...

The FM radio station KAMB broadcasts from an antenna atop a 170
meter tall radio tower at a frequency of 90 MHz with a total
radiated power of 40 kilowatts. Neighbors have complained about
problems they attribute to excessive radiation from the tower, but
the city engineer who measured the radiation level near the base of
the tower found it to be well below the accepted standard. You have
been hired by the HOA to assess the engineer's report. You...
