Ground waves : They follow the curvature of the Earth .They are used for long range navigation. They are low frequency carrier waves (below 2 MHz).

Answer 2

Hi there,


Here's your answer you are looking for .

◼️Electromagnetic waves are actually called the Ground waves that only propagate along an interface between two dielectrics, where one has a negative permittivity. They are called Zenneck waves.


These occur in the surface of earth because the earth is conductive and displays a negative permittivity due to its conductance in the low frequency (below MHz) range.
