Question

What is the ground wave communication?

Answer 1

Ground Wave propagation is a method of radio wave propagation that uses the area between the surface of the earth and the ionosphere for transmission. The ground wave can propagate a considerable distance over the earth's surface particularly in the low frequency and medium frequency portion of the radio spectrum.

Answer 2

⭐ $\sf\underline\red{ Ground \: Wave \: Propagation }$ :- The waves which glide over the surface of the earth are called ground waves.

• The mode of propagation of ground waves is called ground / surface wave propagation.
• The ground wave propagation is useful upto 2 MHz frequencies in AM broadcast with antennas of large size.
