p-wave compression waves
1compression wave — noun see compressional wave * * * a shock wave that compresses the medium through which it is transmitted. Also, compressional wave. Cf. expansion wave. [1885 90] * * * compression wave, Physics. a wave in which the particles of a substance move… …
2Compression (physical) — Compression test on a universal testing machine Physical compression is the result of the subjection of a material to compressive stress, which results in reduction of volume as compared to an uncompressed but otherwise identical state. The… …
3wave motion — ▪ physics propagation of disturbances that is, deviations from a state of rest or equilibrium from place to place in a regular and organized way. Most familiar are surface waves on water, but both sound and light travel as wavelike… …
4Shock wave — Bombshock redirects here. For the Transformers character, see Micromasters#Bombshock. For other uses, see shockwave. Schlieren photograph of an attached shock on a sharp nosed supersonic body. A shock wave (also called shock front or simply shock …
5Longitudinal wave — Longitudinal waves, as known as l waves , are waves that have the same direction of vibration as their direction of travel, which means that the movement of the medium is in the same direction as or the opposite direction to the motion of the… …
6seismic wave — Vibration generated by an earthquake, explosion, or similar phenomenon and propagated within the Earth or along its surface. Earthquakes generate two principal types of waves: body waves, which travel within the Earth, and surface waves, which… …
7Mechanical wave — Ripple (surface wave) in water is a material wave. A mechanical or material wave is a wave that needs a medium to travel. The oscillating material does not move far from its initial equilibrium position, as only the energy is transferred by… …
8Atmospheric wave — An atmospheric wave is a periodic disturbance in the fields of atmospheric variables (like surface pressure or geopotential height, temperature, or wind velocity) which may either propagate ( traveling wave ) or not ( stationary wave ).… …
9sound wave — noun (acoustics) a wave that transmits sound (Freq. 3) • Syn: ↑acoustic wave • Topics: ↑acoustics • Hypernyms: ↑wave, ↑undulation …
10Lee wave — The wind flows towards a mountain and produces a first oscillation (A) followed by more waves. the following waves will have lower amplitude because of the natural damping. Lenticular clouds stuck on top of the flow (A) and (B) will appear… …
