Summary
Description Stokes3 harmonics.svg |
English:
The three harmonics contributing to the surface elevation of a deep water wave, according to
Stokes
' third-order theory. The wave steepness is:
ka
= 0.3, with
k
the
wavenumber
and
a
the wave
amplitude
. For visibility, the vertical scale is distorted by a factor of four, compared to the horizontal scale.
Description: the dark blue line is the surface elevation of the 3rd-order Stokes wave, the black line is the fundamental wave component, with wavenumber k ( wavelength λ, k = 2π / λ), the light blue line is the harmonic at 2 k (wavelength ½ λ), and the red line is the harmonic at 3 k (wavelength ⅓ λ). |
