Okay, so after a little research I think I have a fairly good understanding of wave particle duality. A wave function is just a wave of probability. You don't know where the particle will be until you measure it. Until then, the particle will be in superposition. While it is in superposition, it can interfere with itself, causing an interference pattern to occur in the double slit experiment. The act of measurement means that the position that the particle is in directly affects you, and because it matters which state it is in, it is no longer in superposition and it is placed in one of its possible states. In the double slit experiment, it isn't really a wave, it only acts like a wave because it interferes with itself while it is in superposition. 1. Is this understanding right? 2. How does this work into the wave particle duality? I was EXTREMELY confused by this video: youtube.com/watch?v=_riIY-v2Ym8 I also watched this video: youtube.com/watch?v=wEzRdZGYNvA Thanks if anyone can help!
