The diffraction pattern by double slit is studied by incoming Gaus-sian wave packet subjected to scattering interaction with the wall and a truncation assumption when crossing the slits. Explicit results are valid for sufficiently smooth scattering amplitude. They concern large and narrow aperture of the incoming wave packet. For wave packet localized in spatial region smaller then the aperture of the slits there is no diffraction and the particle behaves classically. For wave packet peaked in the momentum probability distribution there are maxima, superimposed to the canonical diffraction pattern, in correspondence to the edges of the slits. Previous similar results are generalized and improved.

Traditional quantum mechanics explains single-slit diffraction and double-slit interference using wave–particle duality, claiming that photons exhibit both particle and wave properties and can produce self-interference to form light–dark patterns. This paper proposes a new theory: photons always move in uniform linear motion, accompanied by 360° omnidirectional, random, uncontrollable microscopic tremor during propagation. The patterns observed in single-slit and double-slit experiments are macroscopic phenomena formed by collision, reflection, and angular deflection of photons with slit walls due to their inherent tremor, followed by geometric amplification and statistical superposition of numerous photon trajectories. No patterns appear without a baffle because photons do not collide with any wall; no patterns appear with an overly wide slit because photons still pass through without touching the walls. Patterns emerge only when the slit is narrow enough to cause photon–wall collisions. When photons collide with atoms on the slit walls, electrons undergo energy level transitions and emit secondary light; superposition of secondary light from different directions forms alternating bright and dark fringes. This paper designs a carbon nanotube light-absorbing/non-absorbing control experiment and a receiver backplate distance variation auxiliary experiment, both of which provide quantitative and measurable evidence for the theory and form a complete logical closed loop, indicating that the wave–particle duality interpretation is untenable.

The interference and the diffraction are two basic phenomena in physical optics. It has been shown that: in the experiment of a double slit, the patterns depend on the shape of the double slit, e.g., a non-parallel double slit produces the hybrid pattern, the interference pattern embedded in the diffraction pattern; a curved double slit produces Point-Symmetry-Interference-Patterns. In Section 2, we show the pattern evolution of a curved-double slit experiment: near the curved double slit, the pattern is Pre-Particle pattern (at L = 10 mm), then evolve sequentially to Particle pattern (at L = 60 mm), to Transition pattern-1
