Mechanical Waves:
Wave is a disturbance that travels through a medium, whereas the particles constituting the medium do not travel.
The disturbance that travels through a material medium due to the collective vibration of the particles of the medium is known as a mechanical wave.
Characteristics of Mechanical Waves:
1. For the propagation of a mechanical wave, a material medium is necessary. This wave can’t propagate through a vacuum.
2. Each particle of the medium forces the adjacent particles to vibrate, but the particle itself is not carried away from its equilibrium position, rather the wave advances through the medium.
3. The vibrating particles of any material medium have their own mechanical energies. This mechanical energy is transferred from particle to particle due to forced vibration. A wave in motion transfers mechanical energy through the medium. So, this type of wave is called a mechanical wave.
