Double slit over time, single slit in moment

Click For Summary

Discussion Overview

The discussion revolves around a variant of the double slit experiment, specifically examining the outcomes when electrons are sent through one slit at a time, rather than both slits simultaneously. The focus is on whether this approach would yield interference patterns or simply single-slit patterns.

Discussion Character

  • Exploratory, Debate/contested

Main Points Raised

  • One participant proposes a modified double slit experiment where electrons are sent through one slit at a time, questioning the resulting interference pattern.
  • Several participants assert that there would be no double-slit interference, suggesting that only two single-slit patterns would be observed.
  • A question is raised about the experimental confirmation of the claims regarding the absence of interference.
  • Another participant confirms that the assertion about observing single-slit patterns is supported by experiments.

Areas of Agreement / Disagreement

Participants generally agree that the proposed method would not produce double-slit interference, but there is a lack of detailed discussion on the experimental evidence supporting this claim.

Contextual Notes

The discussion does not delve into the specifics of the experimental setups or the conditions under which the claims are made, leaving some assumptions and dependencies on definitions unaddressed.

What happen if you do the following version of the double slit experiment: In first sequence the right slit is open and the left is closed, and a number of electrons are sent through. Then the right slit is closed and the left is opened, and a new sequece of electrons are fired. After completing this, the pattern is observed. Would one see any intereference?

There would be no double-slit interference. You would see two single-slit patterns.

Is that confirmed by experiments?

Of course.
