Here is a noobie thought. We all know the double slit experiment (say for electrons) and the explanation that electrons behave like both wave and a particle. So they pass through both the slits forming the interference pattern. But I think a quanta (electron in this case) behaves like a particle by default. But it also and always has a wave function/property associated with it. Each quanta has a "wave field" around it permeating through space. So, this wave function/property (probably a subtle property for quantas) gets exposed based on what one is doing and the distance between the slits. If the distance between the slits is less than the radius of the wave field, the wave field passes through each slit and then on coming out they interact with one another forming the diffraction pattern. The frequency and amplitude of the resultant wave field will be same even after splitting due to the slits which is why there is a regular pattern. In the double slit experiment the electrons still go through just one of the slits (since they are particles). But the wave field (being energy) associated with each quanta goes into both the slits (if the distance between slits is smaller than the radius of the wave field) producing interference and a diffraction pattern.
