Facts about Sound
- Sound is a continuous longitudinal wave that travels throgh the air.
- The wave is made up of pressure differences.
- Example of generating waves:
- Sound waves have usual wave properties (reflection, refraction,
diffraction, etc.)
- Sound is detected by measuring the pressure level at a point:
- The amplitude of a sound is the measure of displacement of the air pressure wave from its mean:
