According to Max Planck s quantum theory of radiations some phenomenons like photoelectric effect and black body radiations can be explained, if light radiation is supposed to behave as a material particle which is localized at a particular point in space, while according to Maxwell's wave theory of radiation certain other phenomenons like diffraction, interference and polarization can be explained, if light radiation is supposed to behave as a wave which is spread out over space. Thus we find that light shows dual character, i.e. it behaves both as a material particle and as wave.
In 1924 a French physicist, Lonius de Brogile extended the idea of dual character of light to matter particles and suggested that all mater particles in motion (e.g. electrons, protons, neutrons, atoms or molecules etc) have a dual character, i.e. all matter particles posses characteristics of both a material particles and a wave. The wave associated with matter particles is called de Broglie's matter wave. The revulationary idea proposed by de Broglie that a material object posses both the particle and the wave properties known as the wave-particle duality in matter. The idea of wave-particle duality in matter led de Broglieto a very important conclusion that since an electron is also a kind of matter particle, it also, like matter particle, has a dual character i.e. an electron, like all other matter particles, bahave both as a material particle and as awave.
