Particle Model Of Light

Abstract

Two centuries after Thomas Young, with the development of technology, an experimental system that sends photons to the screen one by one was developed and the Young experiment was repeated. Surprisingly, in the double slit experiment, the same interference patterns occurred when individual photons were sent to the slits. This article will show you that it is possible to explain bright-dark fringes with the particle model of light also.

Strange patterns of light

Tao Tang

In a modern version of Young's double slit experiment, a laser beam passes through two narrow slits and creates an interference pattern of bright and dark fringes on a distant screen. We place magnifying glasses between the double-slit and the screen, and when a laser beam passes through the double-slit and magnifying glasses, strange patterns will appear on the screen.

Quantum Optics and Informatics

Davıd L. Andrews, David S. Bradshaw

3.1 Interference of a Single Photon The kinds of study originally conducted by Thomas Young - in particular, the celebrated "double slit" experiment that we briefly examined in Chapter 1 (see Fig. 1) - provide a capacity to reveal far more than the wave nature of light, important as that is. True enough, the observed characteristic fringe pattern, when monochromatic light passes through two closely spaced slits onto a screen, appears to be simply explicable on the basis of waves from each slit undergoing constructive and destructive interference at different positions on the screen. Yet, astonishingly, these patterns of interference are still exhibited when individual photons of a low-intensity input beam reach the screen one at a time, showing that it cannot in fact be a matter of different photons having to interfere with each other. Indeed, Dirac enunciated the general principle that photons can never directly interact with each other. The double slit and other such experiments indicate that each photon interacts in a delocalized, wave-like manner with both slits at the same time. Successive experiments build interference patterns that conform to an exact mathematical distribution formula, but the position at which an individual photon is detected in any particular instance cannot be predicted; this is a quintessential illustration of quantum uncertainty. Using the path integral approach of quantum theory, the phenomenon is more accurately represented by introducing a summation over all possible routes between the source and the screen on which the pattern appears, signifying an entire "lifetime" for each photon involved in the experiment. This relates to the fact that the actual trajectory is unknown without an observation, and thus we only obtain the probabilities of the photon striking the screen at different positions and times; all trajectories (potentialities) must be considered in a superposition. Each route is considered equally probable, and the variation in phase produces quantum interference. The differences in phase of each trajectory, at varying positions on the screen, generates the fringe pattern. An intriguing variation on this experiment involves "marking" the photons so that the actual route of each photon to the screen is known. Remarkably, in such a case, the fringe patterns do not appear because quantum interference cannot occur. A consequence of the observation of the photon route is an effect that, in other quantum mechanical connections, is known as a collapse of the wavefunction. However, it is possible for the fringe patterns to reappear when information on the route of the photons is lost; this is known as a quantum eraser.

The classical double slit experiment–a study of the distribution of interference fringes formed on distant screens of varied shapes

Joseph Ivin Thomas

Abstract The double slit experiment was the first demonstrative proof of the wave nature of light. It was expounded by the English physician-physicist Thomas Young in 1801 and it soon helped lay to rest the then raging Newton–Huygens debate on whether light consisted of a fast-moving stream of particles or a train of progressive waves in the ether medium. In the experiment, light is made to pass through two very narrow slits spaced closely apart. A screen placed on the other side captures a pattern of alternating bright and dark bands called fringes which are formed as a result of the phenomenon of interference. In prior work by the same author, it was shown that the conventional analysis of Young’s experiment that is used in many introductory physics textbooks, suffers from a number of limitations in regards to its ability to accurately predict the positions of these fringes on the distant screen. This was owing to the adoption of some needless and paradoxical assumptions to help simplify the geometry of the slit barrier-screen arrangement. In the new analysis however, all such approximations were discarded and a hyperbola theorem was forwarded which was then suitably applied to determine the exact fringe positions on screens of varied shapes (linear, semi-circular, semi-elliptical). This paper further builds on that work by laying down the mathematical framework necessary for counting fringes and then comparing their distributions on differently shaped screens, using MATLAB software package for numerical–graphical simulation. In addition, a pair of equivalent laws of proportionality are predicted that govern the distribution of fringes independent of the shape of the detection screen employed.

Interference Experiment with a Transparent Mask Rejects Wave Models of Light

John Hodge

Young’s double-slit experiment shows characteristics of light that are modeled as indicating a wave nature of light. Other experiments suggest a particle model of light. An experiment is performed with the Fraunhofer pattern from a first mask impinging on a transparent second mask with a slit. The screen pattern is an interference pattern such as produced in Young’s Experiment. An opaque strip between the first and second mask blocks the light of the center maxima from the first mask. The screen interference fringes remained. Moving the glass mask so the slit is removed from light shows the necessity of a slit in the second mask. This suggests a Newtonian type of light model. This experiment rejects the wave models of light.
