Is this right about the double-slit experiment and quantum physics?? Well I'm trying to understand the double-slit experiment (and quantum mechanics), so could you tell me if this is correct? A photon is fired through two slits at a plate behind the slits. As long as it isn't observed it takes every possible path from the source (which emits the photons) to the plate. Because of that it interferes with itself creating a interference pattern. But if the photon is observed, the wave function collapses (?) and it is forced to only ''choose'' one path, so a single-slit pattern is formed. Please tell me if this is correct and what is wrong and why. Any additional information is appreciated.
