A New Study on the Nature of Single and Double Slit Fringes Theory of Photon Vibration, Collision and Scattering V2

Traditional quantum mechanics explains single-slit diffraction and double-slit interference based on wave-particle duality, claiming that photons possess both particle and wave properties and can self-interfere to form alternating light and dark fringes. This paper puts forward a new theory: photons travel in straight lines. Upon generation, each photon has a fixed transverse vibration direction that maintains a constant angle relative to its propagation axis. A single photon never undergoes random 360° omnidirectional vibration. The omnidirectional vibration observed in natural light is a macroscopic effect formed by the superposition of massive photons each carrying their own unique fixed vibration angles. The fringes observed in single-slit and double-slit experiments are macroscopic patterns formed by geometric amplification and statistical superposition of numerous photon trajectories. These trajectories are deflected and scattered when photons collide with slit walls due to their fixed-angle vibration. No fringes appear without baffles, nor when slits are excessively wide to avoid photon-wall collisions; fringes only emerge when slits are narrow enough to allow photons to collide with wall surfaces. When photons collide with atoms on slit walls, electrons absorb photon energy to jump to higher energy levels and release secondary light during energy-level transitions back to lower states. Superposition of secondary light rays traveling in different directions generates light and dark fringes. This paper retains the carbon nanotube light absorption/non-absorption control experiment and the receiving screen distance variation verification experiment, and adds three new groups of comparative experiments: front polarizer control experiment, gradient wall thickness slit control experiment, and multi-stage polarizer experiment for measuring photon vibration range. Multiple experiments form a complete logical closed loop. At present, there are no publicly available precise quantitative values for the amplitude of photon transverse vibration, and only the approximate variation range can be measured through optical path devices. Multiple experimental observations indicate that interpretations relying on wave-particle duality are untenable.
