3. A wavy pattern of lines produced by the superposition of two patterns having closely spaced, often curved, lines, so that the lines of the two patterns intersect at an acute angle.

The effect may be seen, for example, when the superposed folds of a sheer fabric, such as a window curtain, are observed with transmitted light.
