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. | Whether waves or particles are better suited for describing a system depends on the circumstances.
