How Does the Two Slit Experiment Illustrate Quantum Duality?

Click For Summary

Discussion Overview

The discussion centers around the two-slit experiment and its implications for understanding quantum duality, including concepts such as wave-particle duality, quantum entanglement, and the nature of reality in quantum mechanics. Participants explore various aspects of quantum physics, including the collapse of the wave function, the behavior of photons, and the distinction between classical and quantum realities.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants question whether wave function collapse occurs due to subconscious observation or through mechanical photon detectors.
  • There is a discussion about whether quantum entanglement allows a photon to exist in multiple places simultaneously, with some clarifying that particles are not in two places at once but have probabilities associated with different locations.
  • Participants explore the implications of the two-slit experiment, suggesting it demonstrates both wave and particle behavior, though some express skepticism about the wave-particle analogy.
  • One participant raises the question of how wave collapse occurs in entanglement tests conducted over long distances, noting that current understanding does not clarify the underlying mechanism.
  • There is a debate about whether photons exist in two realities—quantum and classical—with some arguing that most physicists believe there is only a quantum reality that appears classical under certain conditions.
  • Participants discuss the subjective nature of understanding reality, particularly in relation to quantum mechanics and how it contrasts with classical physics.
  • Some express confusion about the nature of light, questioning whether it is a particle, a wave, or something else entirely, with references to external resources for further clarification.

Areas of Agreement / Disagreement

Participants express a range of views on the nature of reality in quantum mechanics, with no consensus reached on whether photons exist in multiple realities or how to interpret wave-particle duality. The discussion remains unresolved regarding the implications of quantum mechanics on classical physics.

Contextual Notes

Participants acknowledge the complexity of quantum mechanics and the limitations of classical intuition in understanding quantum phenomena. There are references to the subjective nature of personal understanding and the challenges of reconciling quantum mechanics with everyday experiences.

Who May Find This Useful

This discussion may be of interest to those new to quantum physics, individuals curious about the philosophical implications of quantum mechanics, and anyone seeking to understand the foundational concepts of wave-particle duality and entanglement.

After abit of research is a photon just a form of dark light waves ?

No.

Correctly - its an excitation of the quantum EM field - but whether that leaves you any the wiser is another matter.

The following would be a good place to start:

I mean the photons are nothing but elecromagnetic waves ... Which is a form of light isn't it ?

Its more complex than that and tied up with Quantum Field Theory which is really not a beginner area.

That said the book I mentioned previously makes a fair fist of it.

Thanks

I'll read the book thanks:)

im just trying to get a closer understanding of the building blocks ( quanta ) of gods creation :)its important to me , but i thought i got that through my first post :)q?... Do you fear the possibility of discovering with "ultra sub-atomic quantascopes" that you may find the worlds building blocks of life amount to nothing but space ?

i made the "ultra sub-atomic quantascope" up for those who didn't notice :)

A couple of days ago i stumble across the two slit vid on youtube and entanglement.

before this day i thought quantum physics was just some kind time travel mumbo jumbo ... I am sure you get my level of noobieness from this :)

ok questions if you would be so kind :)
( don't forget the noobieness ).

1: does the proton wave collapse through subconscious observation or mechanic photon detectors?

2: does the quantum entanglement of the photon being in 2 places at the same time mean that the photon can be in all places ... All the time ?

3:does the two slit experiment mean we know light is a wave but when observed it isn't ? And is this called duality ( two realitys ) ?thank you :)
Ps... I struggled answering the e=mc² question when i signed up for this site lol...that's how noobie i am :)
thanks for your help :)

I don't fear progress.

There have been ideas about that matter is like a knot in space-time - they may be true - or not - who knows - that's what research is for.

Thanks

good luck with the research:)

and the " ultra sub-atomic quantascope" :)

Is the colours from my tv hitting my eyes in small packets ? ( photons of quanta?

Is light shining through glass a simple example of quantum tunnling?

No.

At the beginner level Feynmans book is the best place to start investigating that one:
http://en.wikipedia.org/wiki/QED:_The_Strange_Theory_of_Light_and_Matter

Looking at your questions I really think it would be a good idea to read some basic stuff like what I mentioned before doing any more posts - you will get a lot more out of it that way.

Thanks

Someone said light shining through a glass is a separate phenomena.

im trying to get my head round entanglement first lol

but thanks again :)

Iv learned a lot about light in past day or two:)
the frequencys of colours and how the lower the frequency the lower the energy and something to do with Old red distant light :)

very interesting ... Thanks ;)
