Here's a breakdown:
* Waves: Disturbances that transfer energy without transferring matter.
* Medium: The substance that carries the wave. It can be solid, liquid, or gas.
Examples:
* Sound waves: Travel through air (a gas), water (a liquid), or solids like wood.
* Water waves: Travel on the surface of water (a liquid).
* Light waves: Can travel through a vacuum (no medium) as well as through air, water, and glass.
Important Note: Some waves, like light waves, can travel through a vacuum. This means they don't require a medium to propagate.
