What part of a compressional wave is farther apart?
rarefactions
A: The compressions are the places where the vertical lines are closest together. The rarefactions are the places where the vertical lines are farthest apart.
What is it called if the molecules in the wave are far apart?
Rarefaction in a longitudinal wave is an area in which the molecules of the medium are spread apart.
What are the three parts of a compressional wave?
compression – the part of a sound wave where the molecules are closest together. rarefaction – the part of a sound wave where the molecules are farthest apart. crest – the highest point on a wave. trough – the lowest point on a wave.
What is a crest trough rarefaction and compression?
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.
What is the area of sound where molecules are further apart?
rarefaction
Where the molecules are pushed closer together is an area of compression and when they spring back (even further apart than before) there is an area of rarefaction.
What do we call the part of a compressional wave that is when the waves are squeezed together?
On a compressional wave the area squeezed together is called the compression. The areas spread out are called the rarefaction. The wavelength is the distance from the center of one compression to the center of the next compression.
Is compression a trough or crest?
Key terms
| Term (symbol) | Meaning |
|---|---|
| Crest | Highest point on a transverse wave. Also called the peak. |
| Trough | Lowest point on a transverse wave. |
| Expansion | A point of maximum spacing between particles of a medium for longitudinal waves. |
| Compression | A point of minimum spacing between particles of a medium for longitudinal waves. |
What is compression and 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 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.
Where is the trough of a wave?
What is the meaning of crest and trough?
A crest point on a wave is the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycle.
What is trough and crest on a transverse wave?
A transverse is composed of a crest and trough. Crest is the position of maximum upward displacement while trough is the position of maximum downward displacement.
What is a rarefaction in a longitudinal wave?
What is a compression in a longitudinal wave?
Compression in a longitudinal wave is a region where the particles are the closest together while rarefaction in a longitudinal wave is a region where the particles are spread out. Similar Reading: Transverse Waves.
What is called compression and rarefaction?
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.
What is a compression of a wave?
Compression. A compression is a region in a longitudinal wave where the particles are closest together. Rarefaction. A rarefaction is a region in a longitudinal wave where the particles are furthest apart.
What is the distance between crest and trough called?
wavelength
The horizontal distance between two adjascent crests or troughs is known as the wavelength (λ).
