A wave is defined as a disturbance which is travelled through a particular medium. The medium is material through which a wave is travelled from one to other location. If we take example of a slinky wave which can be stretched from one end to other end and then becomes in static condition. This static condition is called its neutral condition or equilibrium state. 

In the slinky coil, the particles are moved up and down then come into their equilibrium state. This generates disturbance in coil which is moved from one to another end. This is the movement of slinky pulse. This is a single disturbance in medium from one to another location. If it is done continuously and periodical manner then it is called a wave. These are also called energy transport medium. They are found in different shape, show different behaviour, and characteristic properties. On this basis, these are classified mainly in two types that are longitudinal, transverse, and surface waves. Here we are discussing the longitudinal waves, properties and its examples. The movement of wave is parallel to medium of particles in these waves.
