Thermal capillary wave - Wikipedia, the free encyclopedia
Thermal motion is able to produce capillary waves at the molecular scale. At this scale, gravity and hydrodynamics can be neglected, and only the surface tension contribution is relevant. Capillary wa...

This is the fundamental physics of the gravity wave. For a capillary wave the same type of understanding comes about when the dynamic pressure is still determined by the flow speed but the static pressure is now determined by surface tension.

While capillary waves play an important role in the exchange of heat and mass across the air/sea interface, the underlying physics which ... An image of such a capillary wave field is illustrated below, in a 5 inch by 5 inch water tank, where the capillary wavelength is approximately 6 mm. ... Small capillary wave picture...

The amplitude of the capillary wave in a strongly absorbing solution of the dye LDS 751 in ethylene glycol is experimentally studied as a function of laser intensity. Consecutive changes in the predominant mechanism of the excitation with increasing laser intensity are observed and described.

Improvements in this absolute calibration are required before one can determine whether wave turbulence has been observed. [Work supported by the US DOE Division of Engineering and Geophysics and NASA---Microgravity.]

A water wave in which the wave length is less than 2.5 cm is considered to be a capillary wave, while waves longer than 2.5 cm and shorter than 5cm are in an indeterminate zone between CAPILLARY and GRAVITY WAVES.

In reality, capillary waves of arbitrarily small wave-vectors cannot exist. ... Limiting length is gravitational capillary length ... The limiting wave-vector qmin is controlled by one of:

In addition, the dimensionless constant in the relationship between the capillary wave component of momentum roughness length and friction velocity is re-evaluated using both wave tank data and field data.
