Capillary Wave
From Soft-Matter
Capillary wave is a tiny wavlet a few centimeters in wavelength, a few millimeters in height, and with a period of less than half a second. Capillary waves are the most common type of water waves, and apparent when water is calm and flat. These tiny waves would raise when gentle wind breezes through water surface, and decay as soon as the wind dies out.
