WebFirst, waves are supported either by gravity or by capillarity, with a transition at wavelengths close to the centimeter scale, at which the two contributions are deeply entangled. Second, the finite–system size effects induce the existence of discrete Fourier modes that affect the energy cascade. WebGravity: water naturally falls downwards Surface tension: this causes water to cling to the underside of a surface Capillary action: water can also move upwards in cracks or holes with smooth sides which can act as a capillary and …
