rLight is considered to be one of the most mysterious substances in the universe. This paper reveals some unknown characteristics of light. The relation between wave particle duality and light is described. The results show that the interaction and interdependence of photons and light waves are consistent in the process of light propagation in the universe. It is also proposed that all motions with process motion consume energy. The propagation of photons and light waves is the top speed in the universe. It also consumes energy and lists the energy consumption and compensation process of light. The description of light phenomena in the universe is only a conjecture in this paper, which may be an enlightening point for some researchers.esearchers, this may be an enlightening point of view.
