What is ground wave propagation? Write its two properties
Answers
Answer:
Ground wave propagation is a form of signal propagation where the signal travels over the surface of the ground, and as a result it is used to provide regional coverage on the long and medium wave bands.
Answer:
Ground wave propagation is a type of radio propagation which is also known as a surface wave. These waves propagate over the earth’s surface in low and medium frequencies. These are mainly used for transmission between the surface of the earth and the ionosphere. These are made up of the number of constituent waves.
The reason why it is known as a ground wave is that it is the sum of the waves that are reflected by the earth’s surface or any hills. The waves follow the curvature of the earth, enabling them to cover beyond the horizon. Beyond the horizon, the waves get blocked by the curvature of the earth and the signals are produced by the diffracted surface wave.
Following is the table explaining the frequency of ground waves
