Abstract: We introduce a water wave measuring device which is controlled by LabVIEW. Three methods such as standing wave method,phase of traveling wave method and Doppler effect method can be used to measure the dispersion relation of water wave. We compare the advantages and disadvantages of these three methods and put forward some recommendations for improvements.

Key words: dispersion relation of water wave, experimental measurement, standing wave, traveling wave, Doppler effect
