A solid, liquid or gas. Mechanical waves require this to transfer energy.
A type of wave that requires a medium (matter) to transfer energy.

The top peak of a transverse wave.
The bottommost point of a transverse wave.
The area in a compressional wave where there is less matter in an area as the wave passes through the matter.
The area in a compressional wave where there is more matter in an area as the wave passes through the matter.
The distance between two adjacent crests or troughs of a transverse wave.

Matter in the medium vibrates back and forth in the same direction as the energy is transferred.
