+**Wave-particle duality** describes the inherent nature of all matter and energy to exhibit both [Wave](/wiki/wave)-like and [Particle](/wiki/particle)-like properties. Light, for example, can flow like a ripple or strike as a discrete packet, depending on the observation. This fundamental, enigmatic principle lies at the heart of quantum physics.
