2) KERA radio transmits at a frequency of 90.1 MHz. The station broadcasts its signal with...
Radio station KBOB broadcasts at a frequency of 85.7 MHz on your dial using a radio waves that travel at 3.00X10^8 m/s. . Since nearly all of the station's audience is due south of the transmitter, the managers of KBOB don't want to waste any energy broadcasting to the east and west. They decide to build two towers, transmitting at exactly the same frequency, aligned on an east-west axis. For engineering reasons, the two towers must be at least 10...
A radio station transmits isotropically (i.e. in all directions) electromagnetic radiation at the frequency of 98.2 MHz. At a certain distance from the radial station the wave intensity is I = 0.295 W / m ^ 2. a) What will be the intensity of the wave three times the distance of the radial station? b) What is the wavelength of the transmitted signal. c) If the antenna power is 6 MW. At what distance from the source will the wave...
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...

8. A radio station broadcasts at a frequency of 88.1 MHz. At a receiver some distance from the antenna, the maximum electric field of the electromagnetic wave detected is 6 x 10–3V/m. (a) What is the maximum magnetic field? (b) If Ē is in the y-direction and the wave propagtes in the x-direction, what is the direction of the B-field at that moment? (c) What is the wavelength of the electromagnetic wave?
