In this paper, the light wave-particle duality more comprehensively and deeply study; from the medium wave and matter wave; from the energy propagation process of light, from the light energy conversion process (from the fields of physics and chemistry and Biology); from the macro and micro field; from the wave model and particle model. Put forward a more comprehensive and systematic exposition， put forward many new ideas and new concepts. At the same time the light wave-particle duality, tests were carried out on the special and general relativity theory and conclusion. This paper will contribute to the solution of the black hole area of contention.
