What Is An Example Of Rarefaction?

by | Last updated on January 24, 2024

, , , ,

An example of rarefaction is also as

a phase in a sound wave or phonon

. Half of a sound wave is made up of the compression of the medium, and the other half is the decompression or rarefaction of the medium.

What is a rarefaction in a longitudinal wave?

Rarefaction- a region in a longitudinal (sound) wave

where the particles are furthest apart

.

Where is the rarefaction of a wave?

A rarefaction is a

region in a longitudinal wave where the particles are furthest apart

. As seen in Figure 9.2, there are regions where the medium is compressed and other regions where the medium is spread out in a longitudinal wave.

Is a rarefaction a trough?


low point is

called the trough. For longitudinal waves, the compressions and rarefactions are analogous to the crests and troughs of transverse waves. The distance between successive crests or troughs is called the wavelength.

What is rarefaction in a transverse wave?

A rarefaction is

a point on a medium through which a longitudinal wave is traveling that has the minimum density

. … While a transverse wave has an alternating pattern of crests and troughs, a longitudinal wave has an alternating pattern of compressions and rarefactions.

What are the parts of the wave?

  • crest. Noun. the top of a wave.
  • wave. Noun. moving swell on the surface of water.
  • wave height. Noun. the distance between a wave’s trough and crest.
  • wavelength. Noun. the distance between the crests of two waves.
  • wave trough. Noun. the lowest part of a wave.

What occurs during rarefaction?

Rarefaction, in the physics of sound,

segment of one cycle of a longitudinal wave during its travel or motion

, the other segment being compression. … A succession of rarefactions and compressions makes up the longitudinal wave motion that emanates from an acoustic source.

What is the distance between Rarefactions called?

The distance between two consecutive compressions or rarefactions in a wave is called

the wavelength

. Let us know more about the terms compressions, rarefaction and wavelength.

What is a rarefaction curve?

Rarefaction curves are

plots of the number of individuals on the x-axis against the number of species on the y-axis

. Sample sizes (N) may differ, but the relevant sections of the curves can still be visually compared.

What is the period wave?

Wave Period:

The time it takes for two successive crests (one wavelength) to pass a specified point

. The wave period is often referenced in seconds, e.g. one wave every 6 seconds.

Why wave has crest and trough?

The highest surface part of a wave is called the crest, and

the lowest part is the trough

. The vertical distance between the crest and the trough is the wave height. The horizontal distance between two adjacent crests or troughs is known as the wavelength.

Is sound a transverse wave?


Sound waves are not transverse waves because

their oscillations are parallel to the direction of the energy transport. Among the most common examples of transverse waves are ocean waves.

What is wave height called?

The highest part of the wave is called the crest. The lowest part is called the trough. The wave height is the

overall vertical change in height between the crest and the trough

and distance between two successive crests (or troughs) is the length of the wave or wavelength.

What is the compression of a transverse wave?

In a longitudinal wave, the crest and trough of a transverse wave correspond respectively to the compression, and the rarefaction. A compression is

when the particles in the medium through which the wave is traveling are closer together than in its natural state

, that is, when their density is greatest.

Do transverse waves need a medium?

Transverse waves require

a relatively rigid medium

in order to transmit their energy. As one particle begins to move it must be able to exert a pull on its nearest neighbor. If the medium is not rigid as is the case with fluids, the particles will slide past each other.

What is the difference between longitudinal and transverse waves?

In

longitudinal waves

, the vibrations are parallel to the direction of

wave

travel. In

transverse waves

, the vibrations are at right angles to the direction of

wave

travel. Mechanical

waves

cause oscillations of particles

in a

solid, liquid or gas and must have a medium to travel through.
