Fundamental Concepts of Acoustics
Transcript of Fundamental Concepts of Acoustics
What is a wave?
A wave is a disturbance or deviation from a pre-existing condition.
Characteristics of a wave
Waves are carriers of energy, momentum and angular momentum.
Time plays a vital role.
All mechanical waves travel in a material medium.
The wave movement takes place at finite speed.
There is no shape or form restriction.
How do longitudinal waves propagate?
There are two main types of waves
Rarefactions : Pressure and density of the molecules are LOWER than when no wave is passing .
Compressions : Pressure and density of the molecules are HIGHER than when no wave is passing .
Wavelength, Wave Number, Wave Propagation Velocity, Frequency
