When water is disturbed, for instance by dropping a pebble into standing water, water waves are produced which move in circles, energy is passing from the centre to the periphery, however the water itself remains in the same location. Only the energy that is produced at the center on dropping the pebble has moved from the center outwards. The medium for wave motion is water. The water particles vibrate and waves are produced. However when the energy has passed the water particles stop vibrating and they come to their original equilibrium position. Here you see that only energy has moved in the form of waves. This is called wave motion animation.
There are two types of waves-One is “longitudinal” and the other is “transverse” waves.
Longitudinal Waves
If the particles are disturbed in a direction that is parallel to the direction that the wave propagates, it is called a longitudinal wave. The longitudinal wave contains “compressions” in which particles are gathered together and “rarefactions” where particles are spread out. Sound waves are a good Example for longitudinal waves.
