How does a crest move?
How does a crest move? The crest is the highest point particles of the medium reach. The higher the crests are, the greater the amplitude of the wave. In a longitudinal wave, particles of the medium move back and forth in the same direction as the wave.

What is wave length physics?
Definition: Wavelength can be defined as the distance between two successive crests or troughs of a wave. It is measured in the direction of the wave. … This means the longer the wavelength, lower the frequency. In the same manner, shorter the wavelength, higher will be the frequency.
What is the phase difference between the crest of a wave and the adjacent trough?
Since, the phase difference between two successive crests in the wave is [2pi ]. Hence, option ( C ) is the correct answer.
What is the difference between transverse and longitudinal waves?
Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves. … A sound wave traveling through air is a classic example of a longitudinal wave.
Is a compression a crest or trough?
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. |
Which type of wave does not have crests and troughs?
For a transverse wave, this length is commonly measured from one wave crest to the next adjacent wave crest or from one wave trough to the next adjacent wave trough. Since a longitudinal wave does not contain crests and troughs, its wavelength must be measured differently.
What is the time between two wave crests called?
Wave Period: The time it takes for two successive crests (one wavelength) to pass a specified point.
What does a crest look like in physics?
A crest is the highest point the medium rises to and a trough is the lowest point the medium sinks to. Crests and troughs on a transverse wave are shown in Figure 8.2. … A point on the wave is a trough if the displacement of the medium at that point is at a minimum.
What is wave frequency?
In physics, the term frequency refers to the number of waves that pass a fixed point in unit time. It also describes the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
