Ground wave propagation refers to the transmission of radio waves along the surface of the Earth. This type of propagation is commonly utilized for medium and long-distance communication, particularly in the AM radio band. Ground wave signals can follow the curvature of the Earth, allowing for extended coverage compared to line-of-sight transmission.

Why ground wave propagation is not suitable for higher frequency?
Ground wave propagation becomes less suitable for higher frequencies because the signal tends to be absorbed by the ground more efficiently, resulting in shorter range and reduced coverage. At higher frequencies, signals are more likely to be affected by atmospheric conditions and obstacles, making ground wave propagation less reliable compared to other propagation methods like line-of-sight or ionospheric propagation.
What is the direction of wave propagation in a transverse wave?
In a transverse wave, the direction of wave propagation is perpendicular to the direction of the wave oscillation.
Are longitudinal waves traveling through the ground transverse?
No, longitudinal waves are compression waves that travel through the ground by causing particles to move parallel to the direction of the wave propagation. Transverse waves, on the other hand, cause particles to move perpendicular to the direction of the wave propagation.
What is the relationship between the wavelength and the propagation direction in a longitudinal wave?
In a longitudinal wave, the wavelength is the distance between two consecutive points that are in phase with each other. The propagation direction of the wave is the direction in which the wave is moving. The relationship between the wavelength and the propagation direction in a longitudinal wave is that the wavelength is parallel to the propagation direction.
What is the direction of oscillation of the particles of each wave?
In a transverse wave, the particles oscillate perpendicular to the direction of wave propagation. In a longitudinal wave, the particles oscillate parallel to the direction of wave propagation.
