Mechanical wave

A mechanical wave is a type of wave that propagates through a medium (solid, liquid, or gas) due to the oscillation of particles within that medium. Mechanical waves require a physical substance to travel through, distinguishing them from electromagnetic waves, which can travel through a vacuum. Mechanical waves can be classified into two main categories: 1. **Transverse Waves**: In transverse waves, the particle displacement is perpendicular to the direction of the wave propagation.
