WebThe shock wave generated by the explosion is a compression wave, in which the pressure rises from atmospheric pressure to peak overpressure in a fraction of a microsecond. It is followed by a much slower (hundredths of a second) decline to atmospheric pressure. This portion is known as the positive phase of the shock wave. WebIt is defined as a compression wave—a sudden spike in pressure followed by a sudden drop in pressure—formed, for example, when the speed of an object (such as a bullet) is …

Shock wave Definition & Meaning - Merriam-Webster

Blast waves cause damage by a combination of the significant compression of the air in front of the wave (forming a shock front) and the subsequent wind that follows. A blast wave travels faster than the speed of sound and the passage of the shock wave usually lasts only a few milliseconds. Like other types of explosions, a blast wave can also cause damage to things and people by the blast wind, debris, and fires. The original explosion will send out fragments that travel very fast. … WebNov 25, 2013 · When the compression wave hits the bottom of the bottle, the wave transmits its force back up through the liquid as an expansion wave.

A rarefaction is a region in a longitudinal wave where the particles are furthest apart. The region where the medium is compressed is known as a compression and the region where the medium is spread out is known as a rarefaction. حروف الفبا کره ای به فارسی
