Parts of the Wave
Wavelength ( λ ) measured in meters (m)
Frequency ( f ) measured in hertz (Hz)
Distance from crest to crest.
Controls a sound's pitch. (high or low)
- Wavelength increases = frequency decreases
- Wavelength decreases = frequency increases
- Changing wavelength can change the speed of a wave.

The number of complete waves (one wave lenght) that passes a point per second.
Controls a sound's pitch. (high or low)
- Frequency increases = wavelength decreases
- Frequency decreases = wavelength increases
- Changing frequency can change the speed of a wave.
Hertz (Hz) = waves per second

Height of a wave measured from the middle to the crest or trough.
Controls a sound's volume / intensity. (loud or soft)
