9.3 Wavelength and amplitude (ESACU)
- Wavelength
-
The wavelength in a longitudinal wave is the distance between two consecutive points that are in phase.
The wavelength in a longitudinal wave refers to the distance between two consecutive compressions or between two consecutive rarefactions.
- Amplitude
-
The amplitude is the maximum displacement from equilibrium. For a longitudinal wave which is a pressure wave this would be the maximum increase (or decrease) in pressure from the equilibrium pressure that is cause when a compression (or rarefaction) passes a point.
The amplitude is the distance from the equilibrium position of the medium to a compression or a rarefaction.
