There are several forms of waves, their classification being made in accordance with the motion of the individual particles. Most forms of waves can be classified into two types: transverse and longitudinal.
TRANSVERSE WAVE: - "A wave propagating in a medium sets the particles of the medium vibrations. Waves, in which the particles of the medium vibrate along a the perpendicular to the direction of the propagation of waves are called Transverse waves".
EXAMPLE: - There are very much examples of transverse waves in which few examples are as under:
( 1 ) When a stone is dropped into still water pond, circular pattern of waves spread out from the point of impact. Watching the motion of a cork on the surface of the water, one can see that the cork moves up and down locally and the water waves move farther from the point of impact to the edge of the pond.
( 2 ) Light, radio and television signal are best examples of the transverse waves.
For propagation of mechanical transverse waves in a medium, it is essential that the particles of the medium are close enough to exert relatively large forces on one another. In a gas the molecules are too far and hence a transverse wave does not travel through a gas.
LONGITUDINAL WAVES: - "Waves in which the particles of the medium vibrate about their mean positions along the direction of propagation of waves, are known as longitudinal."
It is some time called compressional waves.
EXAMPLES: -
( 1 ) Sound waves in air are longitudinal waves.
( 2 ) Compressional waves begin to travel along a series of masses joined by springs if the series is moved back and forth regularly. Longitudinal waves do not necessarily require a medium of high elasticity. They can travel in solids, liquids and gases.
