aaltopartikelidualismi

Aaltopartikelidualismi, a Finnish term, translates to wave-particle duality. This fundamental concept in quantum mechanics describes the paradoxical behavior of subatomic particles and light, which exhibit characteristics of both waves and particles. Historically, light was understood as a wave, explaining phenomena like diffraction and interference. However, the photoelectric effect, where light striking a metal surface ejects electrons, suggested light also behaves as discrete packets of energy, later termed photons. Similarly, experiments revealed that particles like electrons, previously thought to be solely particles, also exhibit wave-like properties, such as interference patterns when passed through slits. This duality is not about a particle being sometimes a wave and sometimes a particle, but rather that it possesses both aspects simultaneously. The specific manifestation observed depends on the experimental setup. A quantum entity is not a classical wave or a classical particle; it is a distinct quantum object whose behavior can be described using either model depending on the context. This principle is a cornerstone of quantum theory and has profound implications for our understanding of the universe at its most fundamental level.
