What is rarefaction and compression?
Compression and Rarefaction. • Compression- a region in a longitudinal (sound) wave where the particles are closest together. • Rarefaction- a region in a longitudinal (sound) wave where the particles are furthest apart.
What is compression of a wave?
A compression is a region in a longitudinal wave where the particles are closest together. 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.
Why is it called rarefaction?
Therefore, air at higher layers of the atmosphere is less dense, or rarefied, relative to air at lower layers. Thus rarefaction can refer either to a reduction in density over space at a single point of time, or a reduction of density over time for one particular area.
What are the main characteristics of sound wave?
There are five main characteristics of sound waves: wavelength, amplitude, frequency, time period, and velocity. The wavelength of a sound wave indicates the distance that wave travels before it repeats itself.
What are the two main characteristics of sound wave?
Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed.
- Wavelength. Source: www.sites.google.com.
- Amplitude.
- Time-Period.
- Frequency.
- Velocity of Wave (Speed of Wave)
What are the four characteristics of sound?
Every sound has qualities. These qualities relate to different aspects of the sound, such as the volume or the duration. There are four sound qualities: pitch, duration, intensity and timbre.
What are the four characteristics of a wave?
No matter whether you are talking about vibrations or waves, all of them can be characterized by the following four characteristics: amplitude, wavelength, frequency, and speed. The amplitude of a wave can be described as the maximum distance the molecules are displaced from their starting place .
What are 5 characteristics of waves?
Wave properties are elements we can measure for ANY wave. These properties are: amplitude, wavelength, frequency, period, and velocity.
What characteristics can you use to describe a wave?
Wave Characteristics
- Crest = Highest point of the wave.
- Trough = Lowest point of the wave.
- Wavelength = Distance from one crest/trough to the next (m)
- Wave Height = Height from trough to crest (m)
- Wave steepness = ratio of wave height to wavelength.
- Amplitude = distance from the centre of wave to the bottom of the trough (m)
