摘要:

The dispersion relations for waves on liquid surfaces are derived in terms of the Lagrange equations of an oscillator, with gravity and surface tension as restoring mechanisms. This derivation only requires the continuity equation and the assumption of irrotational flow, but not the Bernoulli equation.
