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.Wave Motion AnimationTypes of WavesThere are two types of waves-One is “longitudinal” and the other is “transverse” waves.
Longitudinal WavesIf 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.longitudinal waveLongitudinal wave form 1transvers waveTransverse wavws form1Transverse WavesIn the transverse wave, disturbed particles vibrate perpendicular to the wave's direction. Ocean waves are an example for longitudinal waves.
Conclusion to Wave MotionThe particles woild come back to the position of equilibrium as each type of wave passes through a medium. Therefore, the waves are identified to travel through a particular medium without any displacement of the particles in that medium. There are waves all around us like sound waves, light waves, water waves, electromagnetic waves, heat waves etc. We can see some waves like water waves, however we cannot see sound waves; we can only feel them. Same is the case with light waves and heat waves. The study of waves is very interesting and has a lot to offer for those who are inclined to pursue the subject.
