In physics, ripples (also known as capillary waves) are surface waves on a liquid with wavelengths so short that the liquid's motion is governed almost entirely by surface tension forces. The wavelength of a ripple must be less than
Additional recommended knowledge
For water, λc is found to be 1.7 cm.
In electricity, ripple is the alternating current component from a direct current power supply arising from sources within the power supply. Unless otherwise specified, percent ripple is the ratio of the root mean square value of the ripple voltage to the absolute value of the total voltage.
The ripple voltage can be calculated from the following equations:
