Guided Notes
3 key concepts
- 1
Sound waves are longitudinal waves, meaning their motion occurs in the same direction as the wave travels, creating areas of compression and expansion.
- 2
The pitch of a sound corresponds to the wave's frequency, with higher frequency resulting in a higher pitch, measured in vibrations per second.
- 3
The Doppler effect explains why the pitch of a sound increases as its source moves toward you and decreases as it moves away, due to the changing distance between sound wave peaks.
