Abstract Young’s double slit experiment revived the wave theory of the light. The standard interpretation is that the light behaves as waves before and after passing through the diaphragm of the double slit. Feynman called the double slit experiment the only mystery in quantum mechanics. Recently, the photon chamber has been proposed and utilized to study the behavior of photons near the detecting screen. The experiments show that the light, near the screen, behaves as photons propagating along the straight-line trajectories, and the trajectories distribute as waves. In this article, we utilize two new methods to study experimentally the patterns near the diaphragm of the double slit/cross double slit. The experiments show that, the first time, within certain macroscopic distance from the diaphragm, (1) the pattern is non-interference and thus, the light behaves as photons and produces the “particle pattern” near the double slit; and (2) both the shape and nature of the patterns are distance-dependent; when the distance increases, the non-interference pattern gradually evolves to the interference pattern. The experiments: (1) provide novel phenomena/data for further theoretical development of the optics and for understanding the nature of the light; and (2) show the Feynman’s mystery with different aspect.

Recently, the photon chamber has been proposed and utilized to study the behavior of photons near the detecting screen. The experiments show that the light, near the screen, behaves as photons propagating along the straight-line trajectories, and the trajectories distribute as waves. Furthermore, the photon chamber experiments show that, withing a macroscopic distance from the double slit, the pattern is non-interference, which indicates that the standard double slit experiments violate the standard wave interpretations in the area near the diaphragm. In this article, we utilize two new methods to study how the non-interference pattern (near the double slit) evolving to the interference pattern (far from it). The experiments show, the first time, that (1) the shape of the pattern are distance-dependent, when the distance increases, the non-interference pattern evolves to the interference pattern, which indicates that the non-wave nature and the wave distribution coexist in the same wave experiment; (2) the light beams behave as photons near the double slit. The experiments: (1) provide novel phenomena/data for further theoretical development of the established optics and for understanding the nature of the light; (2) show the Feynman’s mystery in the different perspectives; (3) provide three methods that show the non-wave pattern in standard wave experiments and can be utilized to develop the classical optics further.
Abstract Young’s double slit experiment and Poisson/Arago spot experiment revived the wave theory of the light. The standard interpretation is that the light behaves as waves. Feynman called the double slit experiment the only mystery in quantum mechanics. Recently, the photon chamber has been proposed and utilized to study the behavior of photons near the detecting screen. The experiments show that the light, near the screen, behaves as photons propagating along the straight-line trajectories, and the trajectories distribute as waves. Furthermore, the photon chamber experiments show that, within certain macroscopic distance from the double slit, the pattern is non-interference, which indicates that the standard double slit experiments violate the standard wave interpretations. In this article, we show, the first time, that, within certain macroscopic distance from the ring, the pattern is non-interference, and how the non-interference pattern (near the ring) evolving to the interference pattern (far from the ring). The experiments show: (1) the nature of the patterns is distance-dependent; (2) to certain macroscopic distance from the ring, the light beams behave as particle; (3) when the distance increases, the non-interference pattern evolves to the interference pattern, i.e., the non-wave nature and the wave distribution coexist in the same wave experiment. The experiments: (1) provide novel phenomena/data for further theoretical development of the optics and for understanding the nature of the light.
Young’s double slit experiments revived the wave theory of light. The standard interpretation is that the light behaves as waves before and after passing through the double slit, and the superposition of waves produces the interference pattern. Feynman called the double slit experiment the only mystery in quantum mechanics. In this article, we experimentally show the novel universal phenomena: (1) within macro-distance from the diaphragm, the light rays behave as photons and produce non-interference patterns; while near the screen, the photons produce interference patterns; (2) The non-interference patterns evolve to the interference patterns gradually in the same classical wave experiment; (3) the light is photons before and after passing through the double slit; (4) The convex lens stops the further evolution. The experiments: (1) challenge the wave theories of the light; (2) violate both Bohr’s complementarity principle and wave particle duality; (3) provide profound phenomena for developing optics and for studying the nature of light; (4) suggest that a complete theory should be able to consistently interpret all phenomena, including the non-interference pattern, the interference pattern, and the evolution from the non-interference to the interference pattern in the wave experiment; (5) show a new mystery that photons, as particles, distribute as waves.
The classical interpretation of Young’s double slit experiment is that, before and after passing through the diaphragm of the double slit, the light behaves as waves. Feynman called the double slit experiment “the only mystery [of quantum mechanics]. We have shown for the first time in the classical wave experiments: (1) Particle patterns (non-interference patterns) indicating the particle nature of light are near the diaphragm, and Interference patterns are near the screen; (2) Particle patterns evolve to Transition patterns (non-interference patterns) and finally, evolve to Interference patterns. We proposed Postulates of lens for utilizing lens in wave experiments. In this article, we experimentally suggest that Particle patterns, Transition patterns and Interference patterns simultaneously emerging on the screen in the double slit experiments show that the light beams are photons. The photon chamber shows that the photons distribute as waves in the wave experiments. We suggest that these phenomena and the physical mechanism of them are new mystery.
Abstract The standard interpretation of Young’s double slit experiment is that the light behaves as waves before and after passing through the diaphragm of the double slit. Recently, the photon chamber has been proposed and utilized to study the behavior of photons near the detecting screen. The experiments show that the light behaves as photons propagating along the straight-line trajectories that distribute as waves. Furthermore, the photon chamber placed near the double slit shows the non-interference pattern. In this article we show how the non-interference pattern evolves gradually to the interference pattern in the same cross double slit experiment: (1) the convex lens is placed at 50 mm from the diaphragm of the cross double slit, the non-interference pattern shows and has four primary maximum intensities (Figure (a)); (2) at 100 mm, the four primary maximum intensities disappeared (Figure (b)); (3) at 200 mm (Figure (c)); (4) at 600 mm, the interference pattern shown (Figure (d)), namely the non-interference pattern evolves to the interference pattern. The optics wave and electromagnetic wave theories cannot interpret this phenomenon and thus, is incomplete. This phenomenon provides information for further theoretical development. The cross double slit experiment is complex than the double slit experiments. We briefly discuss the complexity of the cross double slit experiment and show the comparison of both. Declaration : the author declares that there is no potential interest conflict.
Abstract The standard interpretation of Young’s double slit experiment is that the light behaves as waves before and after passing through the diaphragm of the double slit. There is one primary maximum intensity at the central position of the interference pattern. Recently, the photon chamber has been proposed and utilized to study the behavior of photons near the detecting screen. The experiments show that the light, near the screen, behaves as photons propagating along the straight-line trajectories that distribute as waves. Furthermore, the photon chamber placed near the double slit shows non-interference pattern. In this article we show how the non-interference pattern evolving gradually to the interference pattern: (1) at 50 mm from the diaphragm of the double slit, the non-interference pattern shows and has two primary maximum intensities (Figure on left); (2) at 150 mm, there are two shape-changed maximum intensities (Figure at middle); (3) at 400 mm, the non-interference pattern evolves to the regular interference pattern (Figure on right). Those phenomena provide information for theoretical development.
