Study Notes
Sound Wave Characteristics
- Sound waves are mechanical or longitudinal waves caused by vibrating bodies that travel through a medium.
- In a vacuum, no sound can be made because there are no particles to vibrate.
- Longitudinal waves have particles of a medium vibrating in the same direction as the wave travel.
- Sound waves are made up of compressions (particles compressed together) and rarefactions (particles spread out).
Sound Wave Propagation
- Sound waves travel in all directions away from their source.
Types of Sound Waves
- Sound waves have frequencies between 20 Hz and 20 kHz, which is the normal hearing range.
Infrasound
- Infrasound refers to sound frequencies below 20 Hz, which is below the normal hearing range.
Ultrasound
- Ultrasound ranges above 20 kHz, which is above the normal hearing range.
