Yes, that's correct! Mechanical waves are disturbances that propagate through a medium, such as solids, liquids, or gases, transferring energy from one location to another. There are two main types of mechanical waves:
1. **Transverse Waves**: In these waves, the particle displacement is perpendicular to the direction of wave propagation. An example of a transverse wave is a wave on a string or water waves.
2. **Longitudinal Waves**: In these waves, the particle displacement is parallel to the direction of wave propagation. Sound waves in air are a prime example of longitudinal waves, where regions of compression and rarefaction move through the medium.
Because mechanical waves rely on interactions between particles in the medium, they cannot travel through a vacuum. In contrast, electromagnetic waves (like light) do not require a medium and can propagate through a vacuum.
