Capillary waves (ripples) in water Ripples on Lifjord in Øksnes Municipality, Norway Capillary waves produced by droplet impacts on the interface between water and air.. A capillary wave is a wave traveling along the phase boundary of a fluid, whose dynamics and phase velocity are dominated by the effects of surface tension.
Symmetrical ripple. Although symmetrical ripples are also called bi-directional ripples there is a difference between them. Bi-directional ripples are rarely symmetrical due to the difference in force of the two directions, where as the wave formed or oscillation ripples form from the circular water movement pattern of water molecules.
Like the sinuous ripples, this form of ripple is created by unidirectional flow with the dip at an angle to the flow as well as downstream. Linguoid / Lunate Linguoid ripples have lee slope surfaces that are curved generating a laminae similar to caternary and sinuous ripples. Linguoid ripples generate an angle to the flow as well as downstream.
Those seismic waves are like ripples on a pond, the USGS said. The earthquake will be strongest at its epicenter, the point on the surface directly above where the quake started, and the effects ...
Giant current ripples (GCRs), also known as giant gravel bars or giant gravel dunes, [1] are a form of subaqueous dune. They are active channel topographic forms up to 20 m high, which occur within near- thalweg areas of the main outflow routes created by glacial lake outburst floods . [ 2 ]
For example, when leaves alternate up a stem, one rotation of the spiral touches two leaves, so the pattern or ratio is 1/2. In hazel the ratio is 1/3; in apricot it is 2/5; in pear it is 3/8; in almond it is 5/13. [56] Animal behaviour can yield spirals; for example, acorn worms leave spiral fecal trails on the sea floor.

A diagram of the Ripple effect illustrating how the "Weinstein Scandal" led all the way to the rise of the Me Too movement.A ripple effect occurs when an initial disturbance to a system propagates outward to disturb an increasingly larger portion of the system, like ripples expanding across the water when an object is dropped into it.
Faraday waves observed in water in a Petri dish, vibrated at a frequency of about 50 hertz. Faraday waves in a singing bowl. Faraday waves, also known as Faraday ripples, named after Michael Faraday (1791–1867), are nonlinear standing waves that appear on liquids enclosed by a vibrating receptacle.
