Capillary waves are small, rippling waves that form on the surface of liquids, primarily due to the effects of surface tension. These waves typically occur when the wind blows across a body of water, creating tiny disturbances. They are characterized by their short wavelength and high frequency, often seen as small, gentle ripples. These waves are distinct from larger ocean waves, which are influenced by gravity. Capillary waves can be observed in various settings, including lakes and ponds, and play a role in the overall dynamics of water surfaces. Their study is important in fields like oceanography and fluid dynamics.
