Waves are vibrations that propagate. The ideal form of a wave will follow the sinusoid movement. In addition to electromagnetic radiation, and possibly gravitational radiation, which can travel through a vacuum, waves are also present in the medium (which due to form changes can produce spring force) where they can travel and can move energy from one place to another without causing particles the medium moves permanently; ie no mass transfer.
