Study Notes
Sound Waves
- The movement of surrounding air molecules is caused by the vibration of an object, which disturbs the air particles around it.
- The movement of sound waves through the air is kept going by the transfer of energy from one air molecule to another through collisions.
- We can hear a particular vibration if the frequency of the vibration falls within the audible range of human hearing, which is typically between 20 Hz and 20,000 Hz.
- The series of molecular collisions as the sound wave passes through the air is termed a "pressure wave".
- Sound is a form of mechanical energy that is transferred through the vibration of particles in a medium, such as air.
