'''Wave-particle duality''' is the concept that matter and energy have both a [[wave]] nature and a [[particle]] nature. It is a fundamental result predicted by [[quantum mechanics]].
Whether waves or particles are better suited for describing a system depends on the circumstances. For example, light is usually characterized as waves in most every-day applications, but [[photon]]s (light particles) must be considered in some situations, such as the [[photoelectric effect]] and most particle physics experiments.
