Question

What is ground wave communication? On what factors does the maximum range of propagation in this mode depend?

Solution

When the radio waves from the transmitting antenna propagate along the surface of the earth to reach the receiving antenna, it is called ground wave communication. For this type of communication, the frequency range is less than a few MHz. The maximum range depends on the absorption of energy by the earth and also on the initial transmitting power.
