When a small pebble is dropped into a liquid, small waves travel outward as shown in Fig. P7.9. The speed of these waves, c, is assumed to be a function of the liquid density, ρ , the wavelength, , the wave height, h, and the surface tension of the liquid, . Use h, p, and σ as repeating variables to determine a suitable set of pi terms that could be used to describe this problem.
