A wave is a disturbance that travels through space and time, usually by transference of energy. There are two types of waves. Waves are described by a wave function that can take on many forms depending on the type of wave. A mechanical wave is a wave that propagates through a medium due to restoring forces produced upon its deformation. Waves travel and transfer energy from one point to another, often with no permanent displacement of the particles of the medium that is, with little or no associated mass transport.
TYPES OF WAVES:
Waves appear in various forms such as water waves, light waves and sound waves. Listed below are the types of waves.
Longitudinal Wave: When the particles of the medium are displaced parallel to the direction of the propagation of the wave, it is called a longitudinal wave.
Transverse Wave: When the particles of the medium are displaced perpendicular to the direction of the propagation of the wave, it is called a transverse wave.
