A local AM radio station broadcasts at a frequency of 623 kHz. Calculate the wavelength at which it is broadcasting. Wavelength = m (1 kHz = 10 3 sec -1) 6.1
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...

An AM radio station broadcasts an electromagnetic wave with a frequency of 554 kHz, whereas an FM station broadcasts an electromagnetic wave with a frequency of 96.4 MHz. How many AM photons are needed to have a total energy equal to that of one FM photon?
A local AM radio station broadcasts at a frequency of 879 KHz. Calculate the energy of the frequency at which it is broadcasting, Energy = kJ/photon (1 KHz = 103 sec -1)
a radio station broadcasts on a frequency 1010 kilohertz (1010 khz). calculate the period in seconds.
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?
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...
