hullámjelleg

Hullámjelleg, often translated as wave-particle duality or wave nature, is a fundamental concept in quantum mechanics describing the dual behavior of matter and energy. It states that every quantum entity, such as a photon or an electron, exhibits properties of both waves and particles. When behaving as a wave, these entities can demonstrate phenomena like interference and diffraction, which are characteristic wave behaviors. For instance, the double-slit experiment clearly shows electrons creating an interference pattern, a signature of wave propagation.

Conversely, when observed or interacting with other matter, these same entities can act as discrete particles, possessing definite momentum and energy. This particle-like behavior is evident in processes like the photoelectric effect, where light, composed of photons, ejects electrons from a metal surface, behaving as individual packets of energy. The specific manifestation of wave or particle nature depends on the experimental setup and the type of measurement being performed. The concept of hullámjelleg revolutionized classical physics by demonstrating that the fundamental constituents of the universe do not strictly adhere to our everyday macroscopic understanding of either waves or particles, but rather possess a combined nature.
