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, proposed by Louis de Broglie in 1924, is also referred to as the de Broglie hypothesis (/ dəˈbrɔɪ /). Matter waves are referred to as de Broglie waves . </P> <P> The de Broglie wavelength is the wavelength, λ, associated with a massive particle and is related to its momentum, p, through the Planck constant, h: </P>
