Electromagnetic Field Theory - Engineering

Q1:

The ground waves eventually disappear as one moves away from the transmitter because of

A tilting

B maximum single-hop distance limitation

C interference from the sky waves

D loss of line-of sight condition

ANS:A - tilting

In ground wave transmission, the intensity of the signal falls with distance due to its absorption by the ground. So, ground wave propagation cannot take place up to very large distance.
