An experimental study was carried out to understand the kinematics of bichromatic waves. The bichromatic waves are generated at the two dimensional wave tank and measured by the panorama PIV technique. The flow fields can be captured at the space by using PIV techneque. We compared the profile and velocities of wave particles by the experiment with the theoretical results using Stock's 1st and 2nd waves. The wave crests and trough of the highest and lowest point of a bichromatic wave are focused in this study.
