Understanding Interference and Diffraction of Photons and Electrons: a New Approach

Kunwar Jagdish Narain

Published Sep 1, 2017• 0 citations
OpenAlex

Abstract

All electrons, nucleons, and other particles or quanta (because quantum mechanics is applied to all particles, these should be known as quanta) undergo a persistent spin motion without possessing any infinite energy source, and therefore, they should have a unique structure that maintains their spinning and provides all the properties that they display. Additionally, because nothing in nature occurs without a reason or purpose, there should be an explanation for their persistent spinning motion. The photons also possess spin motion that they derive from the orbiting electrons from which the photons are emitted, and not obtain from their unique structure. Therefore, purpose why all electrons, nucleons, and other particles possess persistent spin motion, and unique structures of electrons and nucleons have been determined. The results of the determination of the purpose why all electrons, nucleons, and other particles possess persistent spin motion provide very clear and complete explanations for all related phenomena. Present study is focused on to provide clear and complete understanding of the phenomena of interference and diffraction of electrons and photons.

A NEW QUANTUM THEORY

Kunwar Jagdish Narain

All electrons, nucleons, and other particles or quanta (because quantum mechanics is applied to all particles, these should be known as quanta) undergo a persistent spin motion without possessing any infinite energy source, and therefore, they should have a unique structure that provides their persistent spinning, as well as their other properties that they display. Additionally, because nothing in nature occurs without a reason or purpose, there should be an explanation for the persistent spinning motion. This study determines the purpose behind the persistent spinning motion of quanta, their unique structures, and properties. The results of the determination of the purpose, named “a new quantum theory”, provide very clear and complete explanations for all the phenomena generated due to quanta. Some such phenomena included in this study are: 1) the interference and diffraction of photons and electrons; 2) spectroscopy; 3) transmittance T, which is finite for particles possessing energy E < V0, when V0 is the energy of the potential barrier; 4) rate reduction of increasing velocity in accelerating electrons after they have attained their relativistic velocity; 5) acquisition of elliptical orbits by orbiting electrons despite moving in a spherically symmetric field, and conservations of their energy, momentum, and spin angular momentum.

A New Interpretation of Photon

Kunwar Jagdish Narain

The present interpretation of photon is as: A photon = a quantum of radiation energy + energy hn, where the quantum of radiation energy constitutes the photon and provides the particle like physical existence to it, similarly, as the quantum of charge (-e) constitutes the electron and provides the particle like physical existence to it, and the energy hn enables the photon to travel with velocity c, spin with frequency n (which the photon obtains from the orbiting electron, from which the photon is emitted), scatter electron in Compton scattering, and eject electron penetrating into metals in photoelectric effect. The present interpretation of photon enables to provide very clear and complete explanations of all the phenomena related to photons, including the phenomena of interference and diffraction

Explanation of Quantum Phenomena with a New Model of Photon and Electron Emission, Propagation and Absorption

Henok Tadesse

The puzzles of quantum mechanics are: 1. what is the medium for the photon and for the electron wave? i.e. what is waving? 2. particle interference pattern 3. observer effect. 4. entanglement. In Quantum Erasure and Double-Slit experiments, how does the emitter know to direct the photon two both slits or only to one slit? And how does the detector know where to detect the photons to form an interference pattern and not a bell-shaped (Gaussian) pattern or vice versa? This paper proposes a few, closely related, simple and subtle laws of nature governing quantum phenomena. Some of the findings in this paper are: 1. A photon is emitted in two steps: the creation of photon path and the emission of the photon 2. Although (almost) all of the energy of the photon is localized in space, the photon extends to infinity. An extremely small energy of the photon, which we call the 'precursor wave' in this paper, extends to infinity. The instant the photon is emitted, its precursor wave creates a path to infinity; it appears instantaneously in all its path to infinity, with infinitely small energy density. The precursor wave serves as the 'highway' for the propagation of the main energy packet. However, to conserve the principle of causality, we assume that the tip of the photon propagates at a speed billions times the speed of light. Thus, there are two speeds associated with the photon: the speed we know as c and the speed at which the photon length increases. 2. A photon will be emitted only towards an absorber. A photon is emitted by the interaction of the emitter and a detector. It is obvious that a photon will not be emitted if there is no emitter. Nor will a photon be emitted if there is no detector . Once a photon is emitted, however, it exists objectively, autonomously. The photon is emitted only after its path is determined by the interaction of the emitter and the absorber, at the instant of emission. 3. The photon energy will be concentrated where there is higher wave amplitude, i.e higher intensity of oscillation of electric and magnetic fields. This results in 'dragging' of the electromagnetic energy by the wave, hence eliminating the need for any medium. It is also proposed that single photon interference is a quantum phenomenon whereas two photon interference is a classical phenomenon. Similar laws hold for the electron. The 'medium' for the electron wave is the electron (the electron mass density field) itself. Where there is higher intensity of electron wave/oscillation, there will be higher electron mass density. This means that the electron wave 'drags' the electron with itself. Therefore, no exotic 'medium' is required for the photon and for the electron wave.

New Quantum Theory Explains All the Mysterious Quantum Phenomena

Narendra Swarup Agarwal

The photons & the quantum particles display several mysterious Quantum Phenomena which could not be explained earlier. The New Quantum Theory explains not only the long pending Wave Particle Duality but also all other mysterious Quantum Phenomena. The New Quantum Theory is based on the analogy of the atoms & the solar system and not only supplements but also completes the Quantum Theory. This work explains “how & why” a photon, an electron or quanta generates the electric & the magnetic fields of continuously varying intensities & in the changing directions to form a 3-D Electromagnetic wave. The electromagnetic fields generated by the photons/quantum particles interact with the electromagnetic fields of the mediums (conductor, semicon-ductor or insulator etc.) to display several mysterious Quantum Phenomena. These interactions are strong enough to change the spin, wavelength, amplitude & direction of the quantum particles in the medium. The spin-orbit interlocking/interactions, transverse spin, vortex spin texture & evanescent waves etc. are the results of such interactions. This work explains some of the quantum phenomena in brief so that the various Quantum Phenomena can be modified & developed for the different applications.

Quantum mechanical free electron model

Brian K Tanner

The years of the third decade of the present century were heady times. Old social orders were being swept away, monarchies becoming republics and the United States of America was emerging as a world power. In physics too, revolutions were taking place, none more potent than that which resulted in the emergence of quantum mechanics as a model for the behaviour of sub-atomic particles. It was Newton who first suggested that light was particulate but during the nineteenth century this view had fallen into neglect. Indeed a number of experiments, for example the classic Young's slits experiment, demonstrated quite conclusively that light was a wave motion. How else could interference fringes occur? However, the experiments on the photoelectric effect demonstrated just as conclusively that light energy was carried in packets, or quanta, and that a continuous wave description was not applicable. This ‘wave or particle’ dilemma was not unique to the behaviour of light. J. J. Thompson showed that cathode rays were charged, had a well defined mass and had all the properties expected of a beam of particles. Nevertheless, Davisson and Germer showed that diffraction of electrons could take place, an effect made visually much more dramatic by G. P. Thompson's transmission electron diffraction patterns. Nowadays, electron diffraction is used as a routine analytical tool in all advanced metallurgical and materials science laboratories (Fig. 2.1). Clearly new axioms were required.

Atoms

W. Graham Richards, P.R. Scott

This chapter addresses the question of whether light consists of waves or particles. This issue was resolved in the nineteenth century when it was shown that light could undergo interference and diffraction. The chapter reviews well-known properties and key features of wave motions that emphasize that a point illuminated by two sources of light can nevertheless be in darkness. It also looks at the measurements of diffraction experiments that allowed the wavelengths of different forms of light to be determined. The chapter explains how and why atoms come together to form molecules and illustrates the structure of the Periodic Table. It discusses electrons which are emitted from metal when the energy of the photon exceeds the work function, which implies that a single quantum of energy must be transferred to a single electron.
