Question

What is ground wave propagation?

Answer 1

Ground wave propagation is used for transmitting low frequency signals. In this propagation the signal wave is parallel to ground. While this transmission there is oscillation of wave, so they induce another wave in the surface of the earth as in figure..

Answer 2

$\colorbox{orchid}{ANSWER}$

Ground waves :- these are the waves radiated by antenna that travel parallel Or at lower angles with respect to earth's surface as ground were passes over the surface of earth,its energy is absorbed by earth's atmosphere; therefore,they die out after travelling a short distance.further high frequency waves are absorbed strongly.hence,ground waves propagation can be sustained only at low frequencies 500Hz-1500Hz.
