A study is made of wave propagation on the surface of a liquid in a ripple tank. The waves under study are of the deepwater capillary type that is, short wave length their velocity and mode of propagation are influenced by two independent parameters surface tension and the generated frequency. Since the velocity of wave propagated in a fluid volume is independent of frequency and that of surface waves is not, corrective scaling factors are derived to account for this difference, that is, an expression is developed which correlates the velocity of a wave propagated in a fluid volume with the velocity of a two-dimensional wave on the surface of a fluid. By using properly sized and positioned reflecting boundary surfaces which protrude through the air-liquid interface in the ripple tank, it is possible to study the behavior of sound waves in a fluid volume with prototype reflecting boundary surfaces. A description including photographs of the construction details of the particular ripple tank used in the study is given. Author
