sound waves cause air particles to vibrate back and forth; ripples cause water particles to vibrate up and down. A longitudinal wave is one in which the vibrations of the particles are parallel to ...

The wave travels from left to right, and the particles of the spring vibrate horizontally. In a longitudinal wave, the vibration is parallel to the direction of energy transfer. A ripple tank is a ...
