Rarefaction is defined for the longitudinal waves in which the particles move apart such that it has a low pressure.
| BASIS OF COMPARISON | COMPRESSION | RAREFACTION |
|---|---|---|
| Nature | A compression is a region of high pressure and high density. | A rarefaction is a region of low pressure and low density. |
One may also ask, how are compressions and rarefactions formed?
Compressions and rarefactions are formed during the propagation of longitudinal waves. Waves are mainly divided into two categories, transverse and longitudinal waves. Transverse waves propagate in the form of crests and troughs. On the other hand, a longitudinal wave consists of compressions and rarefactions.
Similarly, what is compression and rarefaction in sound waves Class 9?
Difference between Compression and Rarefaction
| Compression | Refraction |
|---|---|
| It is a region of high pressure | It is a region of low pressure |
| Air particles are closely packed together | Air particles are loosely packed |
What is meant by compression in physics?
compression, decrease in volume of any object or substance resulting from applied stress. Compression may be undergone by solids, liquids, and gases and by living systems.
What is meant by rarefaction in physics?
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 difference between a compression and a rarefaction in a longitudinal wave?
Longitudinal waves show areas of compression and rarefaction : compressions are regions of high pressure due to particles being close together. rarefactions are regions of low pressure due to particles being spread further apart.
What is the difference between a compression and a rarefaction in a sound wave Illustrate your answer with?
Compression is defined for the longitudinal waves in which the particles come closer such that it is at high pressure. Rarefaction is defined for the longitudinal waves in which the particles move apart such that it has low pressure.
What is the difference between compression and rarefaction between a loud sound and a soft sound?
What is the difference in compression and rarefaction between a loud sound and a soft sound? Louder sounds tend to have more of and faster compression. Softer sounds tend to have slower rarefaction.
What is the difference between pitch and intensity of sound?
Intensity is the amount of energy a sound has over an area. Pitch, which depends on frequency, helps us distinguish between low and high sounds. Noise has no identifiable pitch, no pleasing tone, and no steady rhythm.
What is the distance between compression and rarefaction?
The distance between two successive compression and distance between a compression and the adjoining rarefaction is called wavelength.
Where is the rarefaction of a wave?
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.
