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.
