Let's take the archetype of waves, sea-waves. What are they, waves or particles? And lo and behold, they are waves made of particles (water molecules). So if you have a volley ball floating on the surface of the sea, its behavior will be the behavior of a body that interacts with a wave. It is hit by millions of molecules of water, the behavior of which can only be determined on a statistical level, and described by wave-type theories. | |||
However, if instead of a classical ball we consider a body of a size comparable to the size of water molecules (e.g. a molecule of carbon that floats in the sea), its behavior will be the behavior of a body that interacts with particles (the molecules of water). It will collide with individual molecules, and in this case we can determine its behavior by particle-type theories. | |||
So it seems that most if not all waves are waves and particles at the same time, or to be exact, are waves formed by particles. The particle-like "quantum" of a sea wave is a water molecule that moves up and down and that, together with its neighboring molecules that perform the same movement with a phase difference, constitute the wave. If a body of comparable size (the carbon molecule) encounters the "sea wave quantum", it will be knocked off its course by a particle-like collision, even though it interacts with a wave. | |||
So, is a sea wave a wave or a particle? The question becomes rather pointless. It is a wave formed by particles, and when the interaction is on a large scale it manifests as a wave, while if it is on a scale comparable to the size of the particles that form the wave, the existence of the particles becomes evident. Nothing mysterious or paradoxical here. | |||
Of course, this does not address other aspects of the wave-particle duality, such as what happens when elementary particles behave like waves. A first attempt to demystify this matter is the Single Slit Experiment Simulation. | |||
Of course, this leaves us with the big question: what are the "particles" that form the electromagnetic waves? | |||

Let's take the archetype of waves, sea-waves. What are they, waves or particles? And lo and behold, they are waves made of particles (water molecules). So if you have a volley ball floating on the surface of the sea, its behavior will be the behavior of a body that interacts with a wave. It is hit by millions of molecules of water, the behavior of which can only be determined on a statistical level, and described by wave-type theories.
However, if instead of a classical ball we consider a body of a size comparable to the size of water molecules (e.g. a molecule of carbon that floats in the sea), its behavior will be the behavior of a body that interacts with particles (the molecules of water). It will collide with individual molecules, and in this case we can determine its behavior by particle-type theories.
So it seems that most if not all waves are waves and particles at the same time, or to be exact, are waves formed by particles. The particle-like "quantum" of a sea wave is a water molecule that moves up and down and that, together with its neighboring molecules that perform the same movement with a phase difference, constitute the wave. If a body of comparable size (the carbon molecule) encounters the "sea wave quantum", it will be knocked off its course by a particle-like collision, even though it interacts with a wave.
