Here's why:
* Mechanical waves require a medium (like air, water, or a solid) to travel. The particles in the medium vibrate, transferring energy from one particle to the next. This pushing and pulling motion is what propagates the wave.
* Examples of mechanical waves:
* Sound waves: These are longitudinal waves where the particles in the medium vibrate parallel to the direction the wave travels (compression and rarefaction).
* Water waves: These are a combination of transverse and longitudinal waves, where the water molecules move in circles.
