Wave-particle duality proposes that all particles exhibit both wave and particle properties. Light was originally thought to consist solely of waves or particles, but through the work of Planck, Einstein, Bohr and others, it is now understood that particles also have a wave nature, and vice versa. This phenomenon of wave-particle duality is a fundamental principle of quantum physics where matter and light behave as both waves and particles depending on the experimental conditions.

3. Light was thought either to consist of -waves (Huygens) or of -particles (Newton)

5. However, Democritus, who was the original atomist – argued that all things in the universe, are composed of indivisible sub-components (Particles)Democritus

8. Holds that matter and light exhibit the behaviors of both waves and particles, depending upon the circumstances of the experiment.

10. Under certain conditions, such as when we shine it through narrow slits and look at the result, it behaves as only a wave can. Under other conditions, such as when we shine it on a metal and examine the spray of electrons that comes off, light behaves as only particles can.

12. Massive objects exhibit very small wavelengths, so small in fact that it's rather pointless to think of them in a wave form.
