91New Wave (Against Me! song) — New Wave Single by Against Me! from the album New Wave …
92shock wave — An area or sheet of discontinuity (i.e., of abrupt changes in conditions) set up in a supersonic field of flow, through which the fluid undergoes a finite decrease in velocity accompanied by a marked increase in pressure, density, temperature,… …
93pulse wave — n the wave of increased pressure started by the ventricular systole radiating from the semilunar valves over the arterial system at a rate varying between 20 and 30 feet (6.1 and 9.1 meters) per second in different arteries * * * the elevation of …
94blast wave — a violent propagating disturbance, produced by an explosion in air, that consists of an abrupt rise in pressure followed by a drop in pressure to or below atmospheric pressure. Also, blast. Cf. shock wave. [1935 40] * * * …
95expansion wave — In supersonic flow, expansion waves occur when bodies begin to narrow, making more space available. In passing through an expansion wave, air velocity increases, while temperature and pressures are reduced. A simple wave or progressive… …
96normal Mach wave — A wave formed in front of a body when it is moving at the speed of sound. The waves do not move ahead of the body; they bunch up and form a Mach wave. If a Mach wave is at right angles to the direction of movement of the body, the wave is called… …
97radiation pressure — noun the minute pressure exerted on a surface normal to the direction of propagation of a wave • Syn: ↑corpuscular radiation pressure • Hypernyms: ↑pressure, ↑pressure level, ↑force per unit area • Hyponyms: ↑ac …
981912 United States cold wave — The 1912 United States cold wave (also called 1912 cold air outbreak) remains one of the coldest winters yet to occur over the northern United States. It started in December 1911 and continued into late February 1912. Early winterThe freeze… …
99Ram pressure — In physics, ram pressure is a pressure exerted on a body which is moving through a fluid medium. It causes a strong drag force to be exerted on the body. For example, a meteor traveling through the Earth s atmosphere produces a shock wave… …
100sound pressure — Physics. 1. Also called excess sound pressure, instantaneous sound pressure. the difference between the pressure at a point in a medium through which a sound wave is passing and the static pressure of the medium at that point. 2. See effective… …
