How to use it
- Enter wavelength in meters.
- Enter wave period in seconds.
- Calculate speed in m/s and km/h.
Wave Speed Calculator
Calculate average wave speed from wavelength and period.
About the Wave Speed Calculator
Relate the distance between wave crests to the time between them.
Formula
Wave speed equals wavelength divided by wave period.
Example
A 100 m wavelength with a 10-second period gives 10 m/s or 36 km/h.
Notes
This arithmetic relationship uses the supplied wavelength and period and does not model water depth, dispersion or current.
