What is Longitudinal wave?
A '''longitudinal wave''' is a [[wave (physics)|wave]] in which the [[particle]] movement is [[parallel (geometry)|parallel]] to the direction of the wave [[propagation]]. This means that the particles move left and right which in turn makes the other particles start to [[oscillate]]. This creates a wave. Longitudinal waves are also called pressure waves, and [[sound wave]]s are the most common kinds. As with other waves, the [[particle]]s do not move with the wave.
