On the Essence of Wave-Particle Duality

The traditional theory of wave-particle duality holds that microscopic particles are both particles and waves. This view arises from the limitations of early experimental techniques, which equate the statistical wave behavior of a large number of particles directly with the essential properties of a single particle, leading to problems such as logical inconsistency and vague physical picture. Based on modern single-particle emission experiments and basic physical logic, this paper proposes a new explanation: the essential nature of microscopic particles is always particle, not wave; the observed wave property originates from the inherent, continuous, and omnidirectional tiny vibration of particles themselves, which is an external manifestation of particle motion rather than an intrinsic attribute. The strength of a particle’s wave property is closely related to its mass: the smaller the mass, the more significant the vibration and the stronger the wave property; the larger the mass, the weaker the vibration and the less obvious the wave property. Wave-like phenomena such as double-slit interference are the statistical distribution results of landing positions caused by the inherent vibration of numerous particles. This paper reconstructs the physical essence of wave-particle phenomena with concise and self-consistent logic, providing a more intuitive and unified new idea for understanding the microscopic world.
