A type of wave that can travel through empty space as well as through matter is electromagnetic wave.
In transverse waves, the oscillations (vibrations) are at right angles to the direction of travel and energy transfer. Light and other types of electromagnetic radiation are transverse waves. All types of electromagnetic waves travel at the same speed through a vacuum, such as through space.
