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.
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 kind of wave does a jackhammer produce in the ground?
A jackhammer produces longitudinal waves in the ground, meaning the particles of the ground move in the same direction as the wave propagation. This allows the jackhammer to transmit energy efficiently through the ground, breaking up rocks and concrete.
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.
The particles in a wave are moving up and down in comparison to the ground. Which best describes the wave producing this motion?
This describes a transverse wave, where particles move perpendicular to the direction of the wave's propagation. Examples include light and water waves.
What is the different modes of the radio wave propagation?
Ground wave, sky wave and space wave propagation

What is the disadwantege of ground wave propagation?
Ground Wave propagation is sometime unreliable due to the conditions at the surface or topography that the ground waves may encounter. Iron deposits, humidity or water )lack of or over abundance of) ,vegetation etc. On the other hand when using ground wave propagation in barren terrain can be used quite effectively because of the lack of variables. Propagation over large bodies of water (Atlantic, Pacific Oceans) is relatively reliable.
Which seismic wave causes particles in the ground to move perpendicular to the wave's propagation?
S waves, or secondary waves, are transverse seismic waves, meaning that the particles being effected by the wave are moving perpendicular to the wave's propagation.
What is the movement of the ground in a p wave?
In a P-wave (primary wave), the ground moves back and forth in the direction of the wave propagation. This means that the particles in the ground compress and expand as the wave passes through them, creating a push-pull motion similar to a slinky being compressed and stretched.
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 meant by modes of propagation?
Modes of Propagation = different ways to continue and/or increase the number of a given species. Example: sexual reproduction.
What kind of wave does a jackhammer produce in the ground?
A jackhammer produces longitudinal waves in the ground, meaning the particles of the ground move in the same direction as the wave propagation. This allows the jackhammer to transmit energy efficiently through the ground, breaking up rocks and concrete.
What type of propagation is used in telephone communication?
Wave propagation
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.

What is the space wave propagation frequency?
Space wave propagation frequency is nothing special, it is the same frequency of the wave in question, for example WLAN Wifi produces 5.2 GHz radio wave from your computer or from router, so that would be the the space wave propagation frequency in question
