Therefore, they arrive at an observer at different times, an extreme example being an earthquake, where sharp compression waves arrive first, and rocking transverse waves seconds later.
32.
Similarly to the B Ring, the A Ring's outer edge is maintained by an orbital resonance, in this case the 7 : 6 resonance with compression waves.
33.
Another crater named the Shoulder Crater ( " Axlarg�gur " ) produced a column of smoke every 10 s together with loud explosions that created visible compression waves in the smoke.
34.
This creates compression waves in the liquid of the tank which tear the liquid apart, leaving behind many millions of microscopic voids or partial vacuum bubbles ( cavitation ).
35.
Sound waves in solids are composed of compression waves ( just as in gases and liquids ), but there is also a different type of sound wave called a shear wave, which occurs only in solids.
36.
It's a sound wave inside a solid ( a compression wave or " P-wave " . ) The " yank " will travel along the string at the speed of sound in taut string.
37.
Since the compression wave is the fastest of the seismic waves, it is sometimes referred to as the primary wave and is usually more-readily identifiable within the seismic recording as compared to the other seismic waves.
38.
Although the names of Prandtl and Meyer are now universally connected with fans of expansion or compression waves in high-speed gas flows, their leading role in the discovery of oblique-shock waves has been forgotten.
39.
:: The analogy of a line of cars might work, but not as you stated it; it is sort of a complicated analogy since it is a longitudinal wave ( i . e . compression wave ).
40.
So if you insist on this point, the " parts of the tennis balls touching each other " are actually moving at the speed of light, and of course the compression wave doesn't travel faster than that.
