Wave-particle duality is not a lie, but rather a fundamental concept in quantum mechanics that has been extensively verified through experimental observations. It is a description of the behavior of particles at the quantum level, where they can exhibit characteristics of both waves and particles depending on the context of observation.
While it may seem counterintuitive from our everyday macroscopic experience, wave-particle duality has been experimentally confirmed in numerous experiments, such as the double-slit experiment and the diffraction of electrons and photons. These experiments clearly demonstrate the wave-like interference patterns exhibited by particles, indicating their wave-like nature. Conversely, other experiments, such as particle detectors and measurements, reveal the particle-like behavior of these entities.
Wave-particle duality does not mean that particles are simultaneously waves and particles in a classical sense. Instead, it implies that particles exhibit different behaviors under different experimental conditions or measurements. The choice of experimental setup or measurement determines whether we observe particle-like characteristics (e.g., localized position, definite momentum) or wave-like characteristics (e.g., interference, diffraction).
The wave-particle duality is a foundational concept that allows us to understand and describe the behavior of subatomic particles in a quantum framework. It is supported by extensive experimental evidence and is an integral part of our current understanding of quantum mechanics.
