| Why doesn't observing the result collapse the wave the way observing the movement of the photons at the slit does?
The wavefunction of the particle *did* collapse on the final screen, that was an irreversible collision and the particle didn't continue to do anything else. Before the measurement on the final screen the wavefunction was distributed. After, not so.
The observation or non-observation at the slit permitted the particle to still pass through. This shows that even an observation which permits something to pass through will change the behavior of the quantum mechanical particle/wave going through.
Both kinds of observations have an effect.
