What are the movement of a water molecule in a wave?

In a wave, water molecules primarily move in a circular or orbital motion. As the wave passes, they rise and move forward with the crest, then descend and move backward with the trough, returning to their original position after the wave has passed. This movement creates a transfer of energy through the water without significantly displacing the water molecules from their initial location. Consequently, the overall effect is a periodic oscillation rather than a linear movement in the direction of the wave.
