A wave is a way in which energy travels from one place to another. There are many kinds of waves, such as water waves, sound waves, light waves, radio waves, microwaves and earthquake waves. All waves have some things in common.
Difference Between Longitudinal and Transverse Wave. A wave is a disturbance which moves away from what created it and changes the thing that it travels on like the surface of the ocean or the air. This is caused by the transfer of energy that disturbs its medium or channel. There are several types of waves, and two of them are longitudinal and transverse waves. A longitudinal wave is a wave wherein the movement of the channel or medium is in the same direction as the wave. This causes particles to move left and right inducing other particles to oscillate or vibrate. The primary wave or P-wave in an earthquake is an example of a longitudinal wave.
