A compression is a region of high pressure and high density. A rarefaction is a region of low pressure and low density. In the compression, there is temporary decrease in volume of the medium and increase in density. In the rarefaction, there is temporary increase in volume of the medium and decrease in density.
What is the difference between compression and rarefaction?
Facts About Rarefaction

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 a rarefaction in a sound wave?
Rarefaction is the reduction of an item's density, the opposite of compression. Like compression, which can travel in waves (sound waves, for instance), rarefaction waves also exist in nature. A common rarefaction wave is the area of low relative pressure following a shock wave (see picture).
What is the order of compression and rarefaction in a sound wave?
Solution : 1) Compressions and rarefactions in a wave will be in opposite direction.
2) In a compression, all the particles come close, so the density and pressure increases.
3) In a rarefactions, all particles drag back, so the density and pressure decreases.
What causes compression 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.

What causes rarefaction?
Compressions form when wave vibrations push surrounding air particles forward. Alternatively, rarefactions are found in the areas where air particles are more spread out. Rarefactions occur when a lower pressure region of the sound wave is created and air particles are pushed backward.
Why is it called rarefaction?
When rarefaction occurs, the particles in a gas become more spread out. You may come across this word in the context of sound waves. A sound wave moving through air is made up of alternating areas of higher and lower density. The areas of lower density are called rarefactions.
What is the distance between rarefactions called?
The distance between two consecutive compressions or rarefactions in a wave is called the wavelength.
What is the lowest point of the wave?
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.
Which of the following contains compression and rarefactions?
Longitudinal wavesThe correct answer is a longitudinal wave. Longitudinal waves involve compression and rarefaction reactions.
Where is the density of air higher at compressions or at rarefactions?
the more compressed is the air at compressions. the denser the air at rarefactions.
What medium does sound travel fastest through?
solidsSound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster. Sound travels most slowly through gases because the molecules of a gas are farthest apart.
What is the difference between compression and rarefaction?
Compression refers to the region of a longitudinal wave where the particles are closest to each other, while rarefaction refers to the region of a longitudinal wave where the particles are farthest apart from each other.
What is the basic foundation of a longitudinal wave?
This basic foundation of a longitudinal wave, including compression and rarefaction, differs from other waves containing crests and troughs. Sound waves can be classified as mechanical, pressure or longitudinal waves. When sound waves are transferred through a medium, which can be any material via particle-to-particle interaction, ...
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.
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.
What Causes Compression and Rarefaction in Sound Waves?
- Everyone is aware that sound waves travel via media such as air. Whenever an object is in motion, it moves forward and reverses directions. 1. When an item goes ahead, adjacent air particles compress, resulting in a high pressure known as compression. 2. When an item goes backwards, it generates a low-pressure area known as rarefaction. As a result...
Some Facts Regarding Compression
- The gap between particles under compression is shorter than the typical spacing.
- A longitudinal wave is the zone wherein particles are nearest collectively.
- The highest pressure and density are found at the compressor’s centre.
- High-density and high-pressure zone
Some Facts Regarding Rarefaction
- When particles are in rarefaction, the space between them is more significant than the typical distance.
- In a longitudinal wave, it becomes the section where particles are farther apart.
- The rarefaction’s centre is the region with the lowest pressure and density.
- A low-density, low-pressure zone.
Pressure Waves
- Because a sound wave is made up of a regular pattern of high- and low-pressure regions flowing across a medium, it is also known as a pressure wave. If a detector, such as an artificial instrument or the human ear, is used to identify a sound wave, it will notice pressure changes when it infringes on the sensing device. The detectors would recognize a high pressure at one p…
