Study Notes

Sound Waves: Energy Propagation

Sound waves are a form of energy.
They travel through a medium via compressions (higher density) and rarefactions (lower density).
Sound waves are longitudinal waves, meaning the particles oscillate parallel to the direction of the wave's propagation.
In transverse waves, particles oscillate perpendicular to the direction of propagation (e.g., waves on water).
The speed of sound can be influenced by the frequency of the sound and the medium it's traveling through.
Sound waves are characterized by their velocity (speed), frequency, and wavelength.
The direction of oscillation of the sound wave particles is usually perpendicular to the direction of the wave.
