- Is the wave-particle duality a real duality? 10 answers
I'm a high schooler, and I want to clarify what I know about the double-slit experiment. I broke down the double slit experiment into 4 categories: particle w/one & two slit, and wave w/one & two slit.
If we have a single slit w/ waves, they do not interfere, so they create one bright spot on the screen. But if we have a double slit w/ waves, the waves diffract and interfere constructively and destructively to create a band of dark and bright spots on the screen.
On the other hand, if we have one slit w/particles (i.e. electrons), there's just a single bright spot on the screen. And if we have a double slit w/particle, there's two bright spots on the screen. However, light has a wave-particle duality, so if we have a one slit w/light, it interferes with itself (The photons go through both slits and interfere with each other?), and if we have a double-slit, the light behaves like a wave, and thus also interferes with itself?
My question: Am I correct on the above information, and if so, how can a particle interfere with itself? Does it split in half?
