Dual Slit Experiment: Detecting Photons/Particles?

In summary, the conversation discusses the use of a detector to detect photons or particles leaving the emitter and how it affects the wave-like behavior. It is mentioned that placing a detector at the emitter removes the interference pattern, but there are other ways to detect the particles without affecting the interference. The conversation also mentions the terms "double slit" and "erasure" as references for further research. It is concluded that the location of the detector affects the experimental results.

hello - I wonder has anyone tried to place a detector for (photons/particles) just as they leave the emitter. If so does the wave like behaviour disappear?

At the emitter or source does not make a diff.
But there are many ways to detect "which way" or which slit and all remove the wave like interferance. Do a search here on "double slit" or "Erasure".

Yes, RandallB is right, because a detector at the emitter really just turns that into the source. If you still have the same experiment with the source at that point, then you'll still get the same experimental result. If you move the detector closer to one of the slits, then you are in effect doing the experiment with the source at that point, and when you fail to illuminate the other slit with that source, then you will lose your interference pattern.
 

1. What is the Dual Slit Experiment?

The Dual Slit Experiment is a famous scientific experiment that demonstrates the wave-particle duality of light and matter. It involves shining a beam of light or a stream of particles through two parallel slits onto a screen, and observing the resulting interference pattern.

2. How does the Dual Slit Experiment detect photons or particles?

The experiment uses a detector, such as a photographic plate or a sensor, placed behind the slits to detect the photons or particles that pass through the slits. The resulting pattern on the detector screen shows the characteristic interference pattern, indicating the wave-like behavior of the particles.

3. Why is the Dual Slit Experiment important?

The Dual Slit Experiment is important because it provides evidence for the wave-particle duality of light and matter, which is a fundamental concept in quantum mechanics. It also challenges the classical understanding of particles and their behavior, and has implications for our understanding of the nature of reality.

4. What is the significance of the interference pattern in the Dual Slit Experiment?

The interference pattern in the Dual Slit Experiment is significant because it shows that particles can exhibit wave-like behavior, and that their behavior is influenced by being observed. It also demonstrates that particles can interfere with themselves, which is a key concept in quantum mechanics.

5. Is the Dual Slit Experiment still relevant in modern science?

Yes, the Dual Slit Experiment is still relevant and continues to be studied and used in modern science. Its implications and findings have led to further research and developments in the field of quantum mechanics, and it remains an important experiment in understanding the nature of particles and their behavior.
