Input interpretation
phase speed of water wave
Equation
v = sqrt((g tanh(d k))/k) | k = (2 π)/λ | v | wave propagation speed λ | wavelength d | depth of water g | gravitational acceleration k | wavenumber
Input values
wavelength | 1 meter depth of water | 2 meters gravitational acceleration | 9.81 m/s^2 (meters per second squared)
Result
wave propagation speed | 125 cm/s (centimeters per second) = 2.795 mph (miles per hour) = 4.498 km/h (kilometers per hour) = 4.099 ft/s (feet per second) = 1.25 m/s (meters per second)
