A type of wave that can travel through empty space as well as through matter is electromagnetic wave.
But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that light can travel through a vacuumâa completely airless space. (Sound, on the other hand, must travel through a solid, a liquid, or a gas.) Nothing travels faster than light energy.
