In contrast to deep-water waves, shallow ripples on the surface of a pond are due to surface tension. The surface tension ( of water characterizes the restoring force; the mass density ( of water characterizes the water's inertia. Use dimensional analysis to determine whether the surface waves are dispersive (the wave speed depends on the wavelength) or non dispersive (their wave speed is independent of wavelength). [Start by assuming that the wave speed is determined by (, (, and the wavelength (.]
