Traditionally the manifestations of both particle and wave have been considered as complimentary to each other and come about depending on what is being measured. Change what you measure for and it changes reality in other words. Measure for a particle and you won't get the wave effects and measure for the wave and you won't know an electrons location. Out of all the things in Quantum Mechanics Albert Einstein detested this Observer Created Reality most.
Instead of OCR there is something new to understand. Sometimes there can be no wave for an electron. In the Two Slit experiment free electrons are shot through the holes and are detected at a screen on the other side. Without illuminating electrons at the holes they will make a wave pattern at the detection screen on the other side. When adding light to detect them the wave pattern at the detection screen disappears. The electrons tend to pile up directly behind each of the holes and no sign of a wave appears. When light interacts( scatters from) these free electrons their wave collapses temporarily just long enough to pass through a hole without any wave to cause any interference.
Simply put: briefly there is no wave. The wave function collapses temporarily as light is being scattered from the electrons. I believe this is a new phenomenon that can replace the classical Copenhagen interpretation of Observer Created Reality.
There is more to wave-particle duality. Sometimes there's just a particle.
