In the classical double-slit experiment, a beam of light is shone onto a screen through two slits, which results in an interference pattern on the screen.
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.
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. 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.
The interpretation of Young's double slit experiment of diffraction and interference remains controversial. The Scalar Theory of Everything (STOE) model of single photon diffraction is a model with photons being directed by plenum forces as Newton speculated. The STOE simulation of the light diffraction experiments produces the Fraunhofer diffraction pattern on the screen. An experiment used an image resulting from a single slit projected onto a second mask. If the second mask slit is placed at the center of the image, a Fraunhofer diffraction pattern is projected onto the screen. One side of a slit in the minima examined the result of varying the intensity of the illumination across the slit. One slit of two in the minima examined the result of only one of the double slits being illuminated. The resultant patterns on a screen were photographed and are on the opposite side of center from the illuminated side of the second mask. The STOE simulation reproduced the images. The STOE explains several quantum peculiarities with classical processes. These observations do not reject the Newtonian model of diffraction and does reject wave models.
