摘要:

An undergraduate experiment designed to study the dispersion relation and nonlinearity of surface water waves in a trough is discussed. For small amplitudes a resonance technique is used to determine the wave velocity at the frequencies of the lowest modes of the trough. For the finite amplitude case, there is subharmonic nonlinear response for the plane wave mode propagating along the trough’s length as well as waves which reflect from the trough’s sides.
