What is Understanding Sound Waves and Pitch about?

1. Sounds are caused by vibrating objects. Sound waves are longitudinal waves that need a medium like air to propagate. 2. The amplitude of a sound wave depends on its loudness - louder sounds have bigger amplitudes, while softer sounds have smaller amplitudes. 3. The frequency of a sound wave depends on its pitch - higher pitched sounds have higher frequencies, while lower pitched sounds have lower frequencies.
