Surface Tension Effects
Due to surface tension, the dispersion relation changes to:
with γ the surface tension, with SI units in N/m. All above equations for linear waves remain the same, if the gravitational acceleration g is replaced by
As a result of surface tension, the waves propagate faster. Surface tension only has influence for short waves, with wavelengths less than a few decimeters in case of a water–air interface. For very short wavelengths – two millimeter in case of the interface between air and water – gravity effects are negligible.

Famous quotes containing the words surface tension, surface, tension and/or effects:
“Night City was like a deranged experiment in Social Darwinism, designed by a bored researcher who kept one thumb permanently on the fast-forward button. Stop hustling and you sank without a trace, but move a little too swiftly and you’d break the fragile surface tension of the black market; either way, you were gone ... though heart or lungs or kidneys might survive in the service of some stranger with New Yen for the clinic tanks.”
—William Gibson (b. 1948)
“If the man who paints only the tree, or flower, or other surface he sees before him were an artist, the king of artists would be the photographer. It is for the artist to do something beyond this: in portrait painting to put on canvas something more than the face the model wears for that one day; to paint the man, in short, as well as his features.”
—James Mcneill Whistler (1834–1903)
“Many people I know in Los Angeles believe that the Sixties ended abruptly on August 9, 1969, ended at the exact moment when word of the murders on Cielo Drive traveled like brushfire through the community, and in a sense this is true. The tension broke that day. The paranoia was fulfilled.”
—Joan Didion (b. 1935)
“to become a pimp
Or deal in fake jewelry or ruin a fine tenor voice
For effects that bring down the house could happen to all
But the best and the worst of us . . .”
—W.H. (Wystan Hugh)
