Feynman (1956) called the double slit experiment "a phenomenon […] has in it the heart of quantum mechanics. In reality, it contains the only mystery. We cannot make the mystery go away by ‘explaining’ how it works". To study the mystery, the double slit experiments were performed one photon at the time. The photons are described by probability wave function. To interpret, the concept of the collapse of the wave function is utilized. However, the collapse of the wave function leads to the inconsistent/incomplete of the quantum mechanics (Penrose, 2022). In this article, we propose Postulate: the diaphragm, e.g., the slide of the double slit, does not change the nature of the light passing through it. Then we perform multi-experiments to test Postulate, and show that, before and after passing the diaphragm of the double slit, the light is photons. It is photons that produce the wave pattern, e.g., the interference pattern. We referred the phenomena as “PhotonWave Phenomena”.

A complete interpretation should consistently explain all of the experiments, which challenges the existing wave theories. The experiments show the coexistence of particle nature and wave pattern in the same experiment, which violate Bohr’s complementarity principle and the wave interpretations. The experiments provide the comprehensive phenomena for developing theoretical model to study the nature of the light, the complementarity principle, the wave-particle duality, and wave theories.
