Th lti fThe resulting force on a circumference c by surface tension The counterforce by = pressure inside the drop 2 r r2 P c 2 The pressure inside the drop is: P r The pressure inside a bubble is: 4 P r Example of drop of liquidExample of drop of, Likewise at the peak the radius of the stream is greater and, by the same reasoning, pressure due to surface tension is reduced. If this were the only effect, we would expect that the higher pressure in the trough would squeeze liquid into the lower-pressure region in the peak. In this way we see how the wave grows in amplitude over time..

Surface tension is the property of any liquid by virtue of which tries to minimize its free surface area. Surface tension of a liquid is measured as the force acting per length on an imaginary line drawn tangentially on the free surface the liquid.
