Abstract: The waves generated by a sinusoidally oscillating wedge have been measured, analysed and compared with some published theory. The wave celerity, wavemaker efficiency and reflection from the beach have each been considered. A fast Fourier transform technique has been used to determine the magnitudes and relative phases of the fundamental and second harmonic components of the wave at discrete locations in the wave flume. From the overall pattern of waveform variation down the flume, it has been possible to identify the total wave motion in the flume as being the sum of several components. These are a second order Stokes wave, a free second harmonic wave and reflected components at both the fundamental and second harmonic frequencies.
