rarefaction

That will take at least an hour with a rarefaction unit."

Rarefaction is the part of the waves where the molecules are far away from each other.

The elements change into one another by a process of condensation and rarefaction.

An actual example of this is a weapon under development, known as a "rarefaction wave gun".

All other substances are derived from it by condensation and rarefaction.

Sound waves are a lot of compressions and rarefactions.

The sudden compression and rarefaction of the air in its vicinity knocked him off his feet.

This sound can no longer be thought of as a simple wave of compression and rarefaction.

A natural example of rarefaction occurs in the layers of Earth's atmosphere.

Rarefaction can be easily observed by compressing a spring and releasing it.

Offshore exploitation and extraction in deep water are essential for the rarefaction of petroleum.

An area of rarefaction, of low pressure, is formed.

In ecology, rarefaction is a technique to assess species richness from the results of sampling.

The polarity of the stimuli can be rarefaction, condensation or alternating.

At a certain point, about 1961, Coltrane's name became shorthand for the idea of cultural rarefaction.

The bell then repeats the process, creating a repeating series of compressions and rarefactions.

Sound waves have two parts: compression and rarefaction.

Rarefaction is the reduction of an item's density, the opposite of compression.

A common rarefaction wave is the area of low relative pressure following a shock wave (see picture).

The "negative phase" leading the shock front causes sudden rarefaction of the surrounding medium.

He explained natural processes in reference to the rarefactions and condensations of this primary substance.

This causes many lines emanating from point x all in a fan shape, called rarefaction (see figure e).

One compression and one rarefaction make up one longitudinal wave.

This decreasing of pressure is called rarefaction.

The compressions and rarefactions of sound waves push the drum back and forth.
