A 125-kW radio station broadcasts its signal uniformly in all directions.
(a) What is the average intensity of its signal at a distance of 8.05 km from the station?
(b) What is the rms value of the electric field in this radio wave?
(c) If a 1.22-m receiving antenna is oriented parallel to the electric field of the radio wave, what rms voltage appears between its ends? |
