Abstract

Young's experiment plays an important role in Physics,which contains interference,diffraction,modulation and quantum superposition,and not only shows the significance and charm of the wave theory of the light but also demonstrates the profound significance of the quantum theory.For that from several levels of the sub-wave-front two-beam interference,double-slit diffraction,double-slit filter and double-slit quantum superposition,on the initial theory of Young's experiment is discussed in favor of optical theory and technology development.

The Study on the Energy Superposition in the Interference Phenomenon

Zhaoping Yang

The wave optical theory and quantum theory both interpreted Young's Double Slit Interference Experiments.Although one of the two theories is easy to understand,and another theory is difficulty to understand,the results are considered completely.So the students accept wave theory easily,but exclude quantum theory.We observe the energy transfer and the energy superposition of Young's Double Slit Interference experiments by experiment.The experiment shows the interpretation of wave theory in the interference phenomenon is not accord with the practical Phenomenon,but it is accord with the interpretation of quantum theory.The experiments make the student find out the Limitations of wave theory intuitively and understand the related knowledge of quantum theory.

An analysis of Young’s double slit experiment in the light of Schrodinger’s cat

Quantum interference is a challenging phenomenon in quantum optics. According to this principle of superposition of quantum mechanics, elementary particles such as photon can not only be in more than one place at a given time, but that an individual particle can cross its own trajectory and interfere with the direction of its path. Thomas Young devised the double slit experiment to prove that light consisted of waves. Analysis of the double slit experiment and the interference pattern indicates that each photon not only goes through both the slits simultaneously, but traverses every possible trajectory on the way to the target, not just in theory, but in fact. In the present work we have analysed the situation in terms of quantum superposition and Schrodinger cat states in quantum optics. The nature of photon in this analysis is examined

Study on the diffraction-like and interference-like mechanisms of particle flow

Jiqing Zeng, Tianhe Zeng

Abstract The Young's double slit experiment and the electron double slit experiment are generally considered to prove the wave nature of light and electrons. The most obvious sign of the double-slit experiment is that there are bright and dark stripes on the screen. However, people have not carefully studied the causes of the light and dark stripes. Here, we demonstrates that the light and dark fringe in Young's double-slit experiment is not actually the diffraction and interference pattern of light wave, and tries to reveal the real reason for its formation. We have studied the scattering phenomenon of particle flow after passing through the gap, and found that the scattering type and scattering degree of freedom of particle flow are determined by the physical parameters of particles and the gap, and the uniform scattering of particle flow can form a "yes" and "no" discrete distribution pattern on the receiving screen. Based on the "diffraction like" and "interference like" mechanism of particle flow, this paper explains the electron diffraction and interference experiment, as well as the Young's double-slit interference experiment and the diffraction of light through circular holes and plates. This paper negates the wave-particle duality and the de Broglie material wave hypothesis, fundamentally shaking the foundation of modern quantum mechanics, and has great scientific significance.

Study on the Diffraction-like and Interference-like Mechanisms of Particle Flow

Jiqing Zeng, Tianhe Zeng

This paper demonstrates that the light and dark fringe in Young's double-slit experiment is not actually the diffraction and interference pattern of light wave. We investigate the scattering phenomenon after the particle flow passes through the gaps and find that the scattering type and scattering degrees of freedom of the particle flow depend on the physical parameters of the particles and the gaps. When the particle flow undergoes uniform scattering, a uniform "yes" and "no" interspersed discrete distribution pattern will form on the receiving screen. Based on the diffraction-like and interference-like mechanism of particle flow, this paper explains the electron diffraction and interference experiment, as well as the Young's double-slit interference experiment and the diffraction of light through circular holes and plates. This article provides an in-depth discussion on Einstein's concept of wave particle duality and de Broglie's matter wave hypothesis, as well as an analysis of Feynman's experimental idea of electron double slit interference. Our research shows that the matter wave hypothesis is not valid, which has shaken the foundation of modern quantum mechanics and has significant scientific significance. In addition, this study has important application value for the development of technology for detecting and analyzing particles or gaps.

Wave Theory

Muhammad Suhail Zubairy

One of the earliest and most important tenets of quantum mechanics is the wave-particle duality: light behaves sometimes like a wave and at other times as particle and similarly an electron can also behave both like a particle and as a wave. When the formal laws of quantum mechanics are formulated, the central quantity that describes the particles is the wave function. This points to the need for a good understanding of the properties of the waves. This chapter introduces the concepts and most essential applications that are required to follow the discussion of quantum mechanical laws and systems. The basic characteristics of the waves, such as the superposition principle are presented, and the interference and the diffraction phenomena are discussed. The Young’s double slit experiment in analysed and the formation of interference pattern is explicitly shown. The Rayleigh criterion for the microscopic resolution is also derived.

Non-Interference patterns Evolving to Interference Patterns --- Violating Both Classical Optics and Quantum Optics

Hui Peng

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) the light is particles, but waves: within macro-distance from a diaphragm, the light rays produce non-interference patterns; while near the screen, the photons produce orthogonal interference patterns; (2) the non-interference patterns evolve to the orthogonal interference patterns gradually in the same experiment; (3) the evolution of the patterns cannot be interpreted by either classic optics or the quantum optics; (4) the non-interference patterns and the orthogonal interference patterns can show on the screen simultaneously; (5) The convex lens stops the further evolution. The experiments: (1) challenge the classical optics and quantum optics; (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 same wave experiment.
