Waves simply transport energy without any transportation of matter . The energy transportation is carried by a disturbance , which spreads out from a source . We are well familiar with different types of waves such as water waves in the ocean , or gently formed ripples on a still pond due to rain drop . When a musician plucks a guitar-string , sound waves are generated which on reaching our ear , produce the sensation of music . Wave disturbances may also come in a concentrated bundle like the shock waves from an aero plane flying at supersonic speed . What ever may be the nature of waves , the mechanism by which it transports energy is the same . A succession of oscillatory processes are always involved . The wave is generated by an oscillation in the vibrating body and propagation of wave through space is by means of oscillation . The waves which propagate by the oscillation of material particles are known as mechanical waves . There is another class ...
