Is wave-particle duality referring to classical wave?

[Achilles]

Is wave properties of particles referring to classical mechanics waves?

[Markus Hanke]

No, it refers to the fact that quantum objects sometimes behave like waves, and sometimes like particles, depending on what kind of setup you use to observe them. They have both wave and particle characteristics (which are complimentary descriptions of the same entity), hence the name “wave-particle duality”.
