Compression is a region in a longitudinal wave where the particles are closest together. 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 compression and the region where the medium is spread out is known as a rarefaction.
What is the difference between compression and rarefaction?
Facts About Rarefaction
- A rarefaction is a region in a longitudinal wave where the particles are furthest apart.
- A rarefaction is a region of low pressure and low density.
- In the rarefaction, there is temporary increase in volume of the medium and decrease in density.
- The distance between the particles in the rarefaction is greater than the normal distance.

Does rarefaction refer to the compression of air molecules?
When the molecules are pushed closer together it is called compression; when they are pulled apart, it is called rarefaction. The back and forth oscillation of pressure produces a sound wave. The average distance air molecules have to travel before striking one another is called the mean free path.
What does rarefaction mean?
rar·e·fac·tion. (râr′ə-făk′shən) n. 1. The condition of being rarefied. 2. a. A decrease in density and pressure in a medium, such as air, caused by the passage of a sound wave. b.
What is the difference between a compression and a rarefaction?
A compression is a region in a longitudinal wave where the particles are closest together. A rarefaction is a region in a longitudinal wave where the particles are furthest apart.
What is compression and rarefaction in simple words?
Compression is that part of longitudinal wave in which the medium of particles are closer and there is momentary decrease in volume of medium. Rarefaction is that part of longitudinal wave in which the medium of particles apart and there is momentary increase in volume of medium. Physics. Concise Physics.
What is an example of rarefaction?
A natural example of rarefaction occurs in the layers of Earth's atmosphere. Because the atmosphere has mass, most atmospheric matter is nearer to the Earth due to the Earth's gravitation. Therefore, air at higher layers of the atmosphere is less dense, or rarefied, relative to air at lower layers.
Is rarefaction high or low pressure?
These regions are known as compressions and rarefactions respectively. The compressions are regions of high air pressure while the rarefactions are regions of low air pressure.
What causes compressions and rarefactions?
Compressions and Rarefactions Because of the longitudinal motion of the air particles, there are regions in the air where the air particles are compressed together and other regions where the air particles are spread apart. These regions are known as compressions and rarefactions respectively.
Where is the rarefaction on a wave?
These higher pressure areas are called compressions and are found where particles are squeezed together as the wave disturbs the medium. The lower pressure areas or lower density regions are called rarefactions. Rarefactions are sometimes described as the trough of the wave.
What is a wave compression?
9.2. Longitudinal or compression waves are defined as waves where the particle motion is in the same direction in which the wave is propagating. The oscillations in pressure are sinusoidal in nature and are characterised by their frequency, amplitude and wavelength (Figure 9.1).
What is meant by rarefaction in terms of pressure?
Rarefaction is the region of low density, wherein the particles of the medium move away from each other, compression on the other hand, are the regions of high density where the particles of the medium are very close to each other.
How are rarefactions produced?
When a vibrating object moves backward in air as medium, it creates a region of low pressure. This region is called a rarefaction.
Can you have compressions without rarefactions?
The medium is rarefied or compressed relative to its mean pressure. Therefore if there are compressions, there must also be rarefactions.
Is pressure in a rarefaction negative?
As the wave passes, and the particles begin to move left (retuning to their equilibrium positions), the particles are more spread out (rarefaction) and the pressure is negative.
What is the distance between rarefactions called?
The distance between two consecutive compressions or rarefactions in a wave is called the wavelength.
Compression
1.) When longitudinal wave propagates in a medium, medium divides itself in to alternate compression and rarefactions.
Rarefaction
1.) When longitudinal wave propagates in a medium, medium divides itself in to alternate compression and rarefactions.
Which waves have compressions and rarefactions?
Compression and Rarefaction. However instead of crests and troughs, longitudinal waves have compressions and rarefactions.
What is rarefaction in science?
Definition: Rarefaction. A rarefaction is a region in a longitudinal wave where the particles are furthest apart. As seen in the figure below, there are regions where the medium is compressed and other regions where the medium is spread out in a longitudinal wave.
What is the region where the medium is compressed?
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. Compressions and rarefactions on a longitudinal wave.
As nouns the difference between rarefaction and compression
is that rarefaction is a reduction in the density of a material, especially that of a fluid while compression is an increase in density; the act of compressing, or the state of being compressed; compaction.
English
Due to the presence of long-range correlations in language [21], [22] it is not possible to compute accurate measures of the entropy by estimating block probabilities directly.
What is rarefaction in physics?
A rarefaction is a region in a longitudinal wave in which the particles of the medium are further apart than normal and there is a momentary increase in the volume of the medium. It is a region of low pressure and low density. Example:
What is the centre of rarefaction?
The centre of rarefaction is a position of minimum temperature and minimum density. Also Read: Difference Between Sound And Light Waves.
What is compression wave?
A compression is a region in a longitudinal wave in which particles of the medium are closer to one another than they normally are, and there is a momentary reduction in volume of the medium. It is a region of high pressure and high density. Example:
What is the center of compression?
The center of compression is the position of maximum pressure and maximum density.
What is rarefaction in science?
What is general meaning of word Rarefaction. It is a region of low pressure. Example. When a vibrating object moves backward in air as medium, it creates a region of low pressure. This region is called a rarefaction.
How does sound cause rarefaction?
When an object vibrates, it moves in to and fro motion (forward and backward) When object moves in forward motion. It causes nearby air particles to compress.
What is the meaning of compression?
What is general meaning of word Compression? It is a region of high pressure. Example. When a vibrating object moves forward in air as medium, it pushes and compresses the air in front of it. creating a region of high pressure.
What is the name of the region of high pressure that causes air particles to compress?
It causes nearby air particles to compress. This creates a region of high pressure called compression. When object moves back in backward motion. It creates a region of low pressure. This creates a region of low pressure called rarefaction.
