WebThe faster a sound wave travels, the more distance it will cover in the same period. If a sound wave is observed to travel a distance of 700 meters in 2 seconds, then the speed of the wave would be 350 m/s. A slower wave would cover less distance – perhaps 660 meters – in the same time period of 2 seconds and thus have a speed of 330 m/s. WebThe seismic velocity of the uppermost mantle is frequently referred to as the Pn velocity, for “normal P (compressional) wave.”. Pn velocities show a range of values from 7.6 to 8.8 …

WebAfter many vibrations, a series of compressions and rarefactions moves out from the speaker as a sound wave. The red graph shows the gauge pressure of the air versus the distance from the speaker. Pressures vary only slightly from atmospheric pressure for ordinary sounds. WebAug 25, 2009 · A shock wave is a compression wave that, when produced in air, can usually be heard as a sonic boom. The speeds of supersonic objects are often expressed in terms of Mach number—the ratio of the object's speed to the speed of sound in the surrounding air. matt wilson blog
