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 and/or effects:
“The surface of the ground in the Maine woods is everywhere spongy and saturated with moisture.”
—Henry David Thoreau (1817–1862)
“The tension to mother the “right” way can leave a peculiar silence within mother daughter relationships—the silence of a mother’s own truth and experience. Within this silence, a daughter’s authentic voice can also fall silent. This is the silence of perfection. This silence of perfection prevents mothers from listening and learning from their daughters.”
—Elizabeth Debold (20th century)
“The hippie is the scion of surplus value. The dropout can only claim sanctity in a society which offers something to be dropped out of—career, ambition, conspicuous consumption. The effects of hippie sanctimony can only be felt in the context of others who plunder his lifestyle for what they find good or profitable, a process known as rip-off by the hippie, who will not see how savagely he has pillaged intricate and demanding civilizations for his own parodic lifestyle.”
—Germaine Greer (b. 1939)
