From Pathfinder Wiki
In a guitar string for example, the string will vibrate up and down, but the particles that form the string do not move horizontally along the string. Likewise, if you throw a pebble into the water, the water goes up and down and the wave spreads out from the splash point, but there is not a flow of liquid along the surface of the water.
