| the elasticlike force existing in the surface of a liquid caused by asymmetries in the intermolecular forces between surface molecules |
| the ability of a substance to flow; a measure of this ability, the reciprocal of the coefficient of viscosity |

An overall pattern that results when two or more waves interfere with each other, generally showing regions of constructive and of destructive interference. Optical interference patterns are analyzed in devices such as interferometers; the acoustic effect of beats is an example of an interference pattern. |
