Summary
Description Stokes3 amplitude double frequency.svg |
English:
Ratio of the
amplitude
a
2
of the
harmonic
with twice the
wavenumber
(2
k
) to the amplitude
a
of the
fundamental
, according to
Stokes
' second-order theory for
surface gravity waves
. On the horizontal axis is the relative water depth
h
/ λ, with
h
the mean depth and λ the
wavelength
, while the vertical axis is the ratio
a
2
/ a, divided by the wave steepness
ka
(with
k
= 2π / λ).
The blue line is valid for arbitrary water depth, while the dashed red line is the shallow-water limit (water depth small compared to the wavelength), and the dash-dot green line is the asymptotic limit for deep water waves. |
