An 800 kHz radio signal is detected at a point 3 km distant from a transmitter tower. The electric field amplitude of the signal at that point is 610 mV/m. Assume that the signal power is radiated uniformly in all directions and that radio waves incident upon the ground are completely absorbed. The intensity of the radio signal at that point is closest to: 3.5x10-4 W/m2 9.9x10-4 W/m2 O2.5x10-4 W/m2 4.9x10-4 w/m2 7.0x10-4 w/m2

800 kHz radio signal is detected at a point 3.2 km distant from a transmitter tower. The electric field amplitude of the signal at that point is 690 mV/m. Assume that the signal power is radiated uniformly in all directions and that radio waves incident upon the ground are completely absorbed. The average total power radiated by the transmitter is closest to:...

When the Voyager 2 spacecraft passed Neptune in 1989. it was 4.5 Times 10^9 km from the earth. Its radio transmitter, with which it sent back data and images, broadcast with a mere 21 W of power. Assuming that the transmitter broadcast equally in all directions. What signal intensity was received on the earth? What electric field amplitude was detected? The received signal was somewhat stronger than your result because the spacecraft used a directional antenna, but...

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...
