Speed.
It is the distance between two points of maximum compression (or minimum compression).
a shear wave is a wave that moves perpendicular throuth the earth in the form of an earthquake
A shear wave is a type of seismic wave.
A little background first. When an earthquake wave arrives at a seismograph station, the first wave to hit is called the P wave. The second is called the S wave. It turns out that the P wave is a compression wave and the S wave is a shear wave. A compression wave is a direct shove (or tug) parallel to the direction the wave is traveling. A shear wave is a side-to-side shake at right angles to the direction the wave is traveling; transverse to the travel direction, in other words. Therefore the S wave is also known as a transverse wave. The letters P and S actually come from the Latin for First and Second, "primus" and 'secundus." The English "primary" and "secondary" doesn't quite have the same meaning, but it will help you remember which arrives when. "Push" and "Shear" or "Shake" will help you remember which kind of wave has which kind of motion. The time between the P and S wave occurs because the compression wave travels through the Earth faster than the shear wave does. Since the shear wave is slower, the further you are from the epicenter of the earthquake the longer the time between the P and S waves. Seismologists use this to determine how far the epicenter was from the seismograph. And by using distances from three or more seismometer stations at once, they can find the earthquake's epicenter. Another neat thing about the P and S waves is that a compression wave will go through a fluid like water or air, while a shear wave won't. Because S waves won't go through the outer layers of the Earth's core, we know that those layers are liquid.
compression wave is a wave like a sound wave

The three main types of stress in a rock are shearing, tension, and compression.
Tension, Compresion, and Shear :)
When you have the complete compression and rarefaction of a longitudinal wave, that is one complete wave.
The particle motion in shear waves relative to the energy of the wave is downward.
A compression wave.
