The wave-particle duality of photons Tweet In “Nature of light,” we described that light has the properties of wave and a particle. On this page, we will take a second look at that concept. Is light a wave? - Young’s interference experiment - In 1807, an English physicist named Thomas Young asserted that light has the properties of a wave in an experiment called Young’s Interference Experiment. This Young’s interference experiment showed that lights (waves) passing through two slits (double-slit) add together or cancel each other and then interference fringes appear. This phenomenon cannot be explained unless light is considered as a wave. Young’s interference fringes Is light a particle? - Einstein’s light quantum hypothesis - Albert Einstein was a physicist whose life spanned the countries of Germany, Switzerland and America. In 1905 he succeeded in explaining the photoelectric effect which had been unexplainable if one only considers light as a wave. Einstei
