SOUND
- sound produces the particles to vibrate. When sound is created the molecues in the air carry the sound from the place to another by squeezing together (compression) and moving apart (rarefaction) .
- larger amplitude of vibration the louder the sound . The closer the vibrations the higher the frequency and pitch sound.
- Frequency is measure in cycles per second or herts (Hz)
