What is light as a wave?Show answer
The wave model is the working description for the vast majority of classical optics.
What is light as a particle?Show answer
The particle (photon) model is the working description when light interacts with matter through individual quantum events.
What is matter as a particle?Show answer
The particle model is the working description for macroscopic motion and for charged-particle ballistics.
What is matter as a wave?Show answer
The wave model becomes essential when the de Broglie wavelength is comparable to the relevant geometric scale (atomic-spacing crystals, atomic orbits).
