A) induced charges in earth which travel in ground along with the wave, resulting the alternating currents in the earth's surface
B) interference of waves
C) superposition of waves
D) high frequency of signal wave.
Correct Answer: A
Solution :
[a] In ground or surface wave propagation, the loss of power in a signal wave is due to attenuation, i.e., the absorption of energy by the earth which in turn is due to induced charges in earth which travel in ground along with the wave, resulting in the alternating currents in the earth's surface, as well as due to tilting effect, i.e., diffraction of waves.You need to login to perform this action.
