I should have asked this back when Figure 3 came up originally:
In Figure 3, is the total number of hits registered in the detectors equal to the total number of hits registered in Figure 2? Or is it half that number, because (intuitively and probably wrongly?) half the photons are hitting the wall?
Or to state it another way, if you launch a single photon in Figure 3, are we guaranteed to see a hit registered on a detector? Or does that happen just half the time?
