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.

2. IntroductionWave–particle duality prostulates that all particles exhibit both particle and wave properties.

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

4. IntroductionThe first to publicly hypothesize about the nature of light, proposing that light is a disturbance in the element air was Aristotle

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

6. History Through the work ofMax Planck, Albert Einstein, Niels Bohr,and many others, current scientific theory holds that all particles also have a wave nature (and vice versa).

7. This phenomenon has been verified not only for elementary particles, but also for compound particles like atoms and even moleculesSo what is wave-particle duality?The wave particle duality is the principle of quantum physics.

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

9. It is a complex topic, but among the most intriguing in physics.Wave-particle duality in lightLight is able to function as both a particle and a wave, depending on how the experiment is conducted and when observations are made.

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.

11. This multiple personality of light is referred to as "wave-particle duality." Light behaves as a wave, or as particles, depending on what we do with it, and what we try to observe.Wave-particle duality in matterJust like light, matter is also capable of exhibiting properties of both wave-lengths and particles.

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