I would expect that if the slots are closed after the electron has passed through, the interference pattern will remain, unless you detect which slot the electron went through, in which case it will prevent you observing an interference pattern (perhaps because every electron will have a different one). If you detect it on the screen then close the slot, that will not affect the pattern. The electron will be detected where it landed. Lots of electrons detected in this way, with the slots or slot closed after the electron has passed through, will build up the envelope of the expected interference pattern.

If the slots are staggered so that the electron would pass through the slots at different times, and tried to close the later slot for the time the electron would go through it, I would expect the fringes to be eliminated for electrons arriving in the critical time slot. I think you may see reduction in fringe intensity for electrons close to the switching time. I think you would need to open and close the slot when you chose and look for the pattern for electrons arriving on the screen at different time delays from the switching. I would expect you might see the interference vary, perhaps smoothly, as a function of the time of arrival relative to the switching time.

Malcolm White,

Thank you for your answer. I will give it some thought.

Elektronun yarıklardan geçmesi kimyasal bir olay. Bu nedenle yarıklardan herhangi birinin veya ikisinin kapatılması yüzeyde enerji birikimine neden olur. Bu nedenle yarıklar arasındaki mesafe de önemli. Yarıklardan herhangi birinin kapatılması yüzeyde elektron enerjisini hatta kaynaktan fırlatılan enerjisini ve çarpacağı konumu değiştirir ve ön yarığa zarar verme ihtimali var. İki yarığın kapatılması sonucu elektron kimyasal tepkimeye uğrayabilir ve bu nedenle ışıma açığa çıkabilir. Burada elektronun ne kadar bir enerji ile fırlatıldığı önemli.

Şükrü Aktaş, Thank you for taking the time to consider this question. Rich

An electron doesn't pass through just one slit in a two slit experiment (wave) and closing one slit after the electron has passed through means later electrons will see a single slit experiment. Repeated switching between one and two slits should get a superposition of the single and double slit experiments. Since both of these experiments are well known I'm not sure there is much need to do this experiment.

Nicholas Edward Schlotter, thank you for taking the time to answer this question. I'm not sure what interests me is even possible to do. My thoughts are based on an underlying connected 'thread' of space that requires the electron to follow it. Under normal interference the connected thread goes in one slot and out the other. This thread has phasing and would interact with another thread in the screen target. Under this model, closing either slot after passage of the electron through one of the slots would nearly instantly destroy the continuous thread that passed through both slots with one that passed through neither slot and did not produce an interference pattern.

Topaç örneği olabilir. Bu ipi etrafına tamamen sardıktan sonra ipi serbest bırakmaya benzer. Bu olayda sönümleme olur. İp serbest bırakılırsa kendiliğinden topacı başlangıç noktasından bitiş noktasına doğru terk etmeye başlar. Örnek yıldızlar, gezegenler vb. Diğer durumda ise İp bitiş noktasından sökülürse topaç döner ve belirli bir iz bırakır. Bu durum karadeliklerde görülür. Fotonlar saftır ve ışıma yaparak çeşitli görevlerde bulunabilir.

Şükrü Aktaş, thank you for your views.
