(snip)But reduce the amount of light to a *single* photon. And guess what? The interference pattern remains. Thus the *single* particle *must* have gone through both slits.In which case light would always behave as a wave.
AIUI, the single photon does not, and cannot, produce an interference pattern. It either goes through one slit or the other, not both. It behaves like a particle. However, it is impossible to predict which slit the photon will go through, and the interference pattern is produced by many photons, with slightly different and unpredictable starting positions and velocities (velocity as a vector quantity), which have a higher chance of ending on the bright bands of the interference pattern than the dark bands. En masse, the photons behave like a wave.
That's my whole point. Look it up.
According to QT a single photon *can* and *does* go through both slits. It can be demonstrated in the lab. "Particle wave duality". It's arm waving.
