Double slit interference: Part I

Feynman referred to interference as “the only mystery,” and we continue to pursue that idea here by examining the theory behind it with heightened scrutiny. Three interpretations are described: The standard model, Feynman’s sum-over-paths, and Einstein’s photon model. The standard model bases its arguments on the wave function and its subsequent collapse. The sum-over- paths model is equivalent to the standard model, but it explains interference by avoiding use of the wave function and its conceptual problems due to collapse. The Einstein model is the most challenging for it is revolutionary and intuitively demanding. We critique the three models by studying their treatment of polarized light. In Part II, the interference of low intensity light will be discussed.


Feynman a qualifié l'interférence comme le "seul mystère" et nous poursuivons cette idée ici en examinant en profondeur la théorie sous-jacente. Trois interprétations sont décrites: le modèle standard, l’intégrale de chemins de Feynman et le modèle de photon d'Einstein. Le modèle standard fonde ses arguments sur la fonction d'onde et son effondrement ultérieur. Le modèle de l’intégrale de chemins est équivalent au modèle standard mais il explique les interférences en évitant l'utilisation de la fonction d'onde et ses problèmes conceptuels dus à l'effondrement. Le modèle d'Einstein est le plus difficile, car il est révolutionnaire et intuitivement exigeant. Nous critiquons les trois modèles en étudiant leur traitement de la lumière polarisée.


Key words: Photon; Interference; Quantum Mechanics; Maxwell’s Equations; Path Integrals; Standard Model.
