Expert Answer
A sound is a form of energy, just like electricity and light. A sound is made when air molecules vibrate and move in a pattern called waves, or sound waves. Think of when you clap your hands, it produces sound which travel through air (medium) and reach our ear.
- Sound is a wave, a longitudinal wave
- Sound needs a medium to travel
- Waves have an amplitude (volume) frequency (pitch), wavelength (speed), etc
