Részecsketermészetnek refers to the fundamental property of elementary particles in quantum mechanics to exhibit characteristics of both particles and waves. This dual nature is a cornerstone of quantum theory and has profound implications for our understanding of the universe at its smallest scales.

In classical physics, objects are distinctly either particles or waves. A particle, like a billiard ball, has a definite position and momentum at any given time. A wave, like a ripple on water, is spread out and characterized by properties such as wavelength and frequency. However, experiments in the early 20th century revealed that entities we typically think of as particles, such as electrons and photons, can also display wave-like behavior, exhibiting diffraction and interference patterns. Conversely, phenomena that are clearly wave-like, such as light, can also behave as discrete packets of energy, known as photons, when interacting with matter.

This wave-particle duality means that a quantum object cannot be fully described as solely a particle or solely a wave; rather, it possesses aspects of both. The specific aspect that is observed depends on the experimental setup and the nature of the interaction. For example, in the double-slit experiment, electrons fired one at a time will, over time, build up an interference pattern characteristic of waves, even though each electron is detected as a discrete particle. This concept challenges our everyday intuition but is consistently supported by experimental evidence. The mathematical framework of quantum mechanics, particularly the Schrödinger equation, describes these entities using wave functions, which contain probabilistic information about their behavior, encompassing both their particle-like and wave-like tendencies.
