A local radio station is broadcasting a signal. The radio station has a power output of about 467 N. A radio receiver is located 3.04 meters away from the station. What is the intensity of the signal detected by the radio receiver?
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
3. A radio station sends a sinusoidal wave with average power of 50kW. Assume that the transmitter sends the signal with the same value to all direction. Calculate the wave intensity, electric field amplitude, and magnetic field that is detected by a satellite at 100 km away from the antenna.
A local FM radio station broadcasts at an energy of 6.31x10-29 kJ/photon. Calculate the frequency at which it is broadcasting. Frequency = MHz (1 MHz = 10 sec ) A local FM radio station broadcasts at a frequency of 96.7 MHz. Calculate the energy of the frequency at which it is broadcasting. Energy = kJ/photon (1 MHz = 10 sec !) Ultraviolet radiation falls in the wavelength region of 1.00×10-* to 1.00x10-7 meters. What is the energy of ultraviolet radiation...

2) KERA radio transmits at a frequency of 90.1 MHz. The station broadcasts its signal with a power of 100 MW a) What is the wavelength of this radio station's radio signal? b) Assume that KERA broadcasts omnidirectionally (it doesn't, really). Knowing this, what is the intensity of the radio signal for KERA received by a radio a distance of 34.2 kilometers from the broadcast tower? What is the strength of the electric and magnetic fields of the radio signal...
