Longitudinal+Waves

By:allison rowe Longitudinal waves are waves where the vibrations are along or parallel to their direction of travel. This means that the direction of the wave moves in the same direction as the medium (the wave). Particles of the medium(the wave) are displaced in a direction parallel to energy transport, meaning they move in the same direction together. Sound waves are examples of longitudinal waves along with this picture of the springs. The lower picture is another example of the longitudinal waves motion in general.



In longitudinal waves, the medium moves back and forth in the same direction as the wave propagates.
