An AM radio transmitter broadcasts 46.0 kW of power uniformly in all directions. Assuming all of the radio waves that strike the ground are completely absorbed, and that there is no absorption by the atmosphere or other objects, what is the intensity (in W/m2) 30.0 km away? What is the maximum electric field strength (in V/m) at this distance?
Radiation of a single frequency reaches the
upper atmosphere of the earth with an
intensity of 1350 W/m².
What is the maximum value of the electric
field associated with this radiation?
Provide the answer:
V/m
A 2.40–m–diameter university communications satellite dish receives TV signals that have a maximum electric field strength (for one channel) of 8.50 μV/m. If the orbiting satellite broadcasts uniformly over an area of 1.50×1013 m2 (a large fraction of North America), how much power does it radiate??
