Abstract

The double slit has been extended to the cross double slits. The universal phenomena that, in classical double slit wave experiments, the nature and the characteristics of the patterns are distance-dependent. The pattern evolutions have been shown. In this article, we extend the single slit to the cross single slit, e.g., single slits crossing single slits, single slit crossing double slit, etc. Then we experimentally show that, within macroscopic distances from diaphragm, patterns are non-diffraction and gradually evolve to the diffraction patterns near the screen in the same single slit/cross single slit experiment. L: mm Tilt single slit crossing single slit Single slit crossing single slit 4 single slits crossing Single slit crossing Ring Single slit crossing double slit 0* 10 50 110 1100 Challenge is to interpret consistently the non-diffraction patterns, the diffraction patterns, and the pattern evolution phenomena.

Non-Interference Pattern Evolving to Interference Pattern, Non-Diffraction Pattern Evolving to Diffraction Pattern, and Two Non-Diffraction Patterns Evolving to Diffraction-Interference-Hybrid Pattern -Advances in Optical Experiments Demanding New Theory

We experimentally show novel phenomena: (1) in the same double slit or cross double slit experiment, within macroscopic distances from diaphragm, the patterns are non-interference and gradually evolve to the interference patterns near the screen; (2) in the same single slit or cross single slit experiment, within macroscopic distances from diaphragm, the patterns are nondiffraction and gradually evolve to the diffraction patterns near the screen; (3) in the same non-parallel-two-slits experiment, within macroscopic distances from diaphragm, the patterns are diffraction and gradually evolve to the diffraction-interferencehybrid patterns; (4) the diffraction-interference hybrid patterns are angle-dependence. To interpret consistently above phenomena is the challenge to the existing wave theories of the physical optics. Advances in optical experiments demand new theory

Non-Interference Pattern Evolving to Interference Pattern; Non-Diffraction Pattern Evolving to Diffraction Pattern; Two Non-Diffraction Patterns Evolving to Interference-Pattern-Embedded-in-Diffraction Patterns--- Wave-Wave Interference to Photon-Photon Interaction

Hui Peng

We experimentally show novel phenomena: (1) in the same double slit or cross double slit experiment, within macroscopic distances from diaphragm, the patterns are non-interference and gradually evolve to the interference patterns near/on the screen; (2) in the same single slit or cross single slit experiment, within macroscopic distances from diaphragm, the patterns are non-diffraction and gradually evolve to the diffraction patterns near/on the screen; (3) in the same non-parallel-two-slits experiment, within macroscopic distances from diaphragm, the patterns are non-diffraction and gradually evolve to the diffraction-interference-hybrid patterns; (4) the diffraction-interference-hybrid patterns depend on the angle between two slits. Those novel phenomena: (1) challenge the conventional light wave interpretations of the physical optics, the electromagnetic wave and the quantum probability waves, namely, those interpretations are incomplete; (2) challenging Bohr’s complementarity principle and the wave-particle duality; (3) suggest that it is the photon-photon interaction, instead of the wave-wave interference, that produces the phenomena. To interpret consistently above phenomena is the challenge and demands new theory.

Non-interference patterns evolving to interference patterns --- Universal phenomena of single slit, double slit, cross double slit, triple slit, disc ring, 1D grating and 2D grating experiments

Hui Hua Peng

Young’s double slit (and Arago spot) 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. Feynman called the double slit experiment the only mystery in quantum mechanics. In this article, we postulate and experimentally confirm the precise rules of convex lenses. Based on those Postulates, we study the evolution of the patterns of single slit, double slit, triple slit, cross-double slit, disc ring, 1D-grating and 2D-grating experiments. The experiments show, for the first time, the novel universal phenomena: (1) Within a certain macroscopic distance from the diaphragm (Zone-1), light behaves as photons and produces a non-interference pattern, while near the screen (the far field, Zone-3), the photons produce an interference pattern, while between Zone-1 and Zone-3 (Zone-2), the photons produce an non-interference pattern; namely the nature and characteristics of the pattern are distance dependent; (2) The non-interference pattern evolves to the interference pattern gradually in the same experiment; (3) The convex lens stops the evolution of the patterns. The experiments provide profound phenomena/data for further theoretical development of optics and for understanding the nature of light. We suggest that a complete theory should be able to interpret the non-interference pattern in Zone-1, the non-interference pattern in Zone-2, and the interference pattern in Zone-3; and the evolution from one pattern to another.
