Hint: A mechanical wave is a wave that is caused by matter oscillations and thus transfers energy through a medium. Although waves can travel great distances, the medium of transmission—the material—can only go so far. As a result, the oscillating material stays close to its initial equilibrium position.
Complete answer:
Mechanical waves are divided into two categories:
1.Longitudinal waves: In this form of wave, the particle movement is parallel to the motion of the energy, i.e. the medium displacement is in the same direction as the wave. Sound waves and pressure waves are two examples. The particle displacement in a longitudinal wave is parallel to the wave propagation path. A wave like this is made up of many compressions and rarefactions. In the longitudinal wave, the rarefaction is the furthest apart, and the compression is the furthest apart. Since the atoms in the compressible medium are closer together, the longitudinal wave travels further with a higher index of refraction.
2. Transverse waves: It occurs when the motion of the particles is at right angles or perpendicular to the motion of the energy. A transverse wave is almost like light. Other examples include polarised waves and electromagnetic waves. The particle displacement in a transverse wave is perpendicular to the wave propagation direction. All points on a wave oscillate along paths at right angles to the direction of the wave's advance in a transverse wave.
Note: The direction of movement of the individual particles of the medium relative to the direction that the waves propagate is one way to categorize waves. On this basis, waves are divided into two distinct categories: transverse waves and longitudinal waves.Waves come in a variety of shapes and sizes. Although all waves have some basic characteristics and behaviors in common, some waves can be distinguished from others by observable (and non-observable) characteristics.
