Ground wave, sky wave and space wave propagation
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.
s wave!
better over water
the P wave
The general term for what a wave travels through is a medium, but in the case of earthquakes the wave travels through the ground.

The S-wave is the secondary seismic wave.
A ground plane is use in radio where the wave length is less than 1 half wave. It produced a false ground (Earth plane) making an image of a 1/4 wave signal reflect on to the aerial creating a half wave image. This improves the efficiency or the aerial, extending it's range. Ground planes are used when the wavelength if the aerial is short or when the earth does not provide a good enough electrical path to ground. They can also be used to distort the polar pattern of the signal.
The answer is Tsunami ????. Did this help u.
The surface wave that shakes the ground in a rolling elliptical shape is called the Rayleigh wave. Rayleigh waves travel along the surface of solids and cause both vertical and horizontal ground movement, resulting in a rolling motion that resembles ocean waves. They are typically the most destructive type of seismic wave during an earthquake.
The space wave is the wave that propagates directly through free space, rather than via some other object or medium like the ground.
