A 2.80 m diameter university communications satellite dish receives TV signals that have a maximum electric field streng
A 2.80 m diameter university communications satellite dish receives TV signals that have a maximum electric field strength (for one channel) of 7.80 μV/m. (See the figure below.) Q (a) What is the intensity (in watts per meter squared) of this wave? W/m² (b) What is the power received (in watts) by the antenna? W (c) If the orbiting satellite broadcasts uniformly over an area of 1.50 x 10¹3 m² (a large fraction of North America), how much power (in watts) does it radiate? W
