The study of liquid surface waves with a smartphone camera and an image recognition algorithm

Simple experimental setups are designed for observing liquid surface waves, studying the dispersion relation and obtaining the liquid surface tension coefficient. In addition, the relationship between temperature and the liquid surface tension coefficient is verified. We take pictures of the surface wave patterns with a smartphone camera and measure the wavelength with software analysis based on image recognition. The experiment is performed not only with common devices and simple operations, but also with the student's own smartphone. As a result, the experiment itself is easy and convenient to carry out, which stimulates undergraduates' interest in this experiment.
