<human>:  What is the significance of the wave-particle duality in quantum mechanics?
<bot>: The wave-particle duality is an important concept in quantum mechanics, since it allows for a more complete understanding of the behavior of particles on an atomic and subatomic level. It states that all particles, including photons, electrons, and other particles, can exhibit both wave-like behavior and particle-like behavior. This means that particles can display properties of both waves
 •
 • such as interference and superposition
 •
 • along with particle-like properties, such as particle localization and momentum. This has significant implications in the understanding of the quantum world, and is a key concept in quantum mechanics.
