Double-Slit Experiment (or Two-Slit Experiment)

Peng, Hui

Young's double slit experiments representing the mystery of quantum mechanics have been descripted by wave theories. To study the mystery, the double slit experiments were extended to the cross-double slit experiments. A description should explain all the double slit and cross-double slit experiments consistently. To test the wave description, the two postulates are proposed, which state that before passing through the double slit and before landing on the detector, photons behave as particles, but not as waves. To test the two postulates, the comprehensive double slit/cross-double slit experiments are proposed and performed. By placing shields and/or blockers near the detector/screen, the comprehensive double slit/cross-double slit experiments show that the fringes are created independently and partially, which discloses the particle nature of photons in the double slit/crossdouble slit experiments and violates the wave descriptions. The comprehensive double slit/cross-double slit experiments provide the comprehensive phenomena for developing theoretical model to study the mystery of double slit, complementarity principle, wave-particle duality, and wave theory of light.

We have performed cross-double-slit experiment and delayed-choice-cross-double-slit experiment, denoted as extended double-slit experiments. The cross-double-slit experiments show that the cross-double-slit apparatus creates not only two interference patterns, but also four cross-interference-patterns, which are created by two double-slit. The delayed-choice-cross-double-slit experiments disclose new phenomena: (1) photons behave as both wave and particle in the same experiment simultaneously, which violate Bohr’s complementarity; (2) the cross-interference-pattern is created by one double-slit and one single-slit; (3) photons passing through the same slit behave as both wave and particle, referred it as the Wave-Particle-Paradox, which demands extensive study. We suggest to re-study wave-particle duality.

The single slit and double slit (where two slit are parallel) experiments are two profound experiments in Physical/quantum optics. In this article, we study the variety of the optical experiments, including cross single slit, curve-single slit, non-parallel double slit, curve-double slit, non-parallel curve-double slit experiments. The experiments show the following novel patterns. Hourglass-shape diffraction pattern of a Curve-single slit Ring-shape interference pattern with spot at center of a ring Hybrid pattern of a non-parallel double slit Arc-shape and point-symmetry interference patterns of a curve-double slit Butterfly-shape interference pattern of a non-parallel-curve-double slit The experiments show that it is photons that produce wave-like patterns, referred to it as PhotoWave phenomena. It is a challenge to interpret all PhotoWave experiments consistently and completely.
