What DOESN'T Move: The medium itself (if there is one) doesn't travel along with the wave.
* Think of a rope: When you shake one end, the wave travels along the rope, but the rope itself doesn't go anywhere. It just wiggles up and down.
* Ocean waves: The water molecules don't travel across the ocean. They move in a circular motion, transferring energy along.
What DOES Move:
* Energy: The primary thing that travels in a wave is energy. This energy can be transferred through a medium, like sound waves traveling through air, or through a vacuum, like light waves from the sun.
* Disturbance: A wave is essentially a disturbance that propagates through a medium or space. This disturbance can be a change in pressure (sound), an electric and magnetic field (light), or a change in the position of particles (water waves).
In Summary:
Waves are not the movement of matter itself, but rather the movement of energy and a disturbance through a medium or space. The medium particles oscillate or vibrate around a fixed point, but they don't travel along with the wave.
