A type of wave that can travel through empty space as well as through matter is electromagnetic wave.
Matter waves are a central part of the theory of quantum mechanics, being an example of waveâparticle duality. All matter can exhibit wave-like behavior. For example, a beam of electrons can be diffracted just like a beam of light or a water wave. The concept that matter behaves like a wave is also referred to as the de Broglie hypothesis (/dÉËbrÉÉª/) due to having been proposed by Louis de Broglie in 1924. Matter waves are referred to as de Broglie waves.
