what properties are particles and waves
Waveâparticle duality is the fact that every elementary particle or quantic entity exhibits the properties of not only particles, but also waves. It addresses the inability of the classical concepts particle or wave to fully describe the behavior of quantum-scale objects.As Einstein wrote: .iels Bohr regarded the duality paradox  as a fundamental or metaphysical fact of nature. A given kind of quantum object, will exhibit sometimes wave, sometimes particle, character, in respectively different physical settings.
