DUAL PROPERTY OF ELECTRON Incase of light, some phenomenon like interference diffraction etc,.. can be explained if light is suposed to have wave character .however certain other phenomenon such as black body radiation and photo electric effect can be explained only if its believed to be a stream of photons ( photons is defined as is an elementary particle the quantum of light and all others forms of electro magnetic radiation and the force carrier for the electro magnetic force ) i.e ., has particle character. thus light said to have a dual character. such studies on light were made by einstein in 1905. Louis de broglie, afrench physicist , in 1924 , advanced an idea that like photons , all material particles such as electron , photons,atoms,molecules,a piece of chalk,a piece of stone or iron ball possessed both wave character as well as particle character .The wave associated with a particle is called wave matter.
