A type of wave that can travel through empty space as well as through matter is electromagnetic wave.
A second way that waves are characterized is by the types of matter they are able to travel through. Electromagnetic waves (including light) can move through a vacuum. Physical waves require matter through which to propagate. Physical waves are further distinguished by the phases of matter through which they can move.
