A news broadcaster is to be aired from a newsroom of a television station. The news is to be transmitted by radio waves. How long will it take the news to reach a person watching the television who is 750 km away from the station’s transmitter?
Radio receivers can comfortably pick up a broadcasting station's signal when the electric field strength of the signal is about 10.0 mV/mmV/m.
If a radio station broadcasts in all directions with an average power of 54.0 kWkW, what would be the maximum distance at which you could easily pick up its transmissions? (Atmospheric conditions can have major effects on this distance.)
Express your answer with the appropriate units.
Energy carried by an EM wave coming through the air can be used to light a bulb that is not connected to a battery or plugged into an electric outlet. Suppose a receiving antenna is attached to a bulb and the bulb is found to dissipate a maximum power of 1.05 W when the antenna is aligned with the electric field coming from a distant source. The wavelength of the source is large compared to the antenna length. When the antenna is rotated so it makes an angle of 71.0° with the incoming electric field, what is the power dissipated by the bulb?
