Abstract : A spectrum analyzer is used to examine the ultrasonic spectra produced when large amplitude ultrasonic waves are caused to resonate in a water-filled cavity. The cavity, consisting of a plane transducer and concave reflector, produces frequency components which appear to be the result of beating (a linear process) and/or modulation (a non-linear process). A scheme for labelling the frequency components is developed. (Author)
