B Interference fringes, what if you sample them?

Click For Summary
The discussion centers on a thought experiment involving a Young's Slit experiment with photons and the implications of sampling interference fringes using a telescope. Participants debate whether interference occurs while photons travel through the air gap or only after they interact with the target screen. There is contention over whether a telescope can resolve the slits, with some arguing that directional information is lost during the photon’s transit, affecting the interference pattern. The conversation highlights the complexities of quantum mechanics and classical wave theory in understanding photon behavior. Ultimately, the experiment raises questions about the nature of interference and the role of measurement in determining outcomes.

classical approximations of QM phenomena are not wanted in this forum,

What you are talking about has nothing to do with QM. It can all be explained with classical physics. But you insist on introducing QM into it and in doing that end up promulgating misinformation. For example you speak of individual photon paths - in QM there is no such thing - and that is just one of many errors in what you write. I am asking you to listen to what others in this thread are telling you rather than try to tell them and get it completely wrong.

Ah, but look at the bigger picture, Bill.

In other words ignore what is going on Quantum Mechanically, which is very complicated, and delve into something you have concocted yourself. As I said you really need a solid state physicist to sort this out using QM. We have some people here with that background, but its way beyond a B level thread nor is there is any gain in doing so since its all capable of being explained using classical physics.

Really this thread should be moved out of the QM forum and into the classical physics forum, but for now I will leave it here and see how it progresses.

Thanks
Bill

Vanadium has been telling me, since post #5 on page 1, that the experiment can't work.
He or she has used strong language without reprimand.
And has implicitly painted me as a fool, unable to understand a two-term equation or check external resources.

I have listened and asked for clarification, to no end.

As moderator, and as a person capable of understanding QFT, would you now please step in?

He has done nothing wrong IMHO. However you are not listening to what others, including him, are telling you and instead post misinformation. This has lead to a thread that is not going anywhere. Because of this the thread will now be locked and the mentors will discuss any further action.

Thanks
