Explanation of wave-particle picture, light

Click For Summary

Discussion Overview

The discussion revolves around the concept of wave-particle duality in quantum physics, particularly focusing on the implications of recent imaging of light that purportedly captures both wave and particle characteristics. Participants explore the nature of quantum objects and the interpretation of their properties in relation to classical physics.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions the validity of capturing a simultaneous wave-particle picture, suggesting it contradicts the idea that waves are merely mathematical probabilities that manifest as particles upon measurement.
  • Another participant asserts that there is no "wave-particle duality," arguing that quantum objects are neither waves nor particles but possess properties that can be measured as either depending on the context.
  • A request for clarification is made regarding whether the imaging represents wave properties and particle properties simultaneously, and whether classical concepts of waves and particles are applicable to quantum mechanics.
  • Concerns are raised about the credibility of the source linked by the original poster, with a claim that the article misrepresents the significance of the research and the concept of wave-particle duality.

Areas of Agreement / Disagreement

Participants express differing views on the interpretation of wave-particle duality and the nature of quantum objects. There is no consensus on the validity of the original article or the implications of the imaging discussed.

Contextual Notes

Participants note that the terminology of waves and particles in quantum mechanics differs from classical definitions, leading to potential misunderstandings. The discussion highlights the complexity of interpreting quantum phenomena and the challenges of applying classical concepts to them.

Sincé I am not a physicist, but study a lot of quantum physics of my own, I hope you excuse my incomplete knowledge.

I have been thinking about the following: If a picture of a simultaneous wave-particle was taken, doesn´t that
contradict the fact that waves actually don´t exist, they are just mathematical probabilities that become information when measured, and therefore particles?
So how can you have mathematical probabilities in a picture with its complementary particle.
Or did they take the picture of the mathematical probabilities in the process of becoming particle?

Your link leads to a statement "can't be found".

There IS no "wave particle duality". There are quantum objects which are not waves OR particles. They are quantum objects. If you measure their wave properties, you see wave properties, but they are not classical waves. If you measure their particle properties, you see particle properties, but they are not classical particles.

What you say is very interesting Phinds, but could you expand a Little more?
So the picture is not about waves and particles but about wave properties and particle properties at the same time?
Does this also mean that the concept of real wave and real particle belong to Newtonian physics?

Uh, which part of

was not clear? I was responding to the concept of "wave particle duality" which has been dead in serious physics for about 90 years.

The concepts of waves belongs to both classical physics and quantum mechanics, but it is not the same concept, just the same word and the problem is that "wave particle duality" is trying to apply the classical concepts to quantum objects.

Neither. That iflscience.com article is complete garbage, misstating what the researchers did and the significance of their work. And how do I know this even though the URL you posted leads to "page not found" error? First, I recognize the article name in the URL, and you'll find some discussion of it in other threads here. Second, I have your summary of what the article said.

Stuff like this is why PhysicsForums has the rule about acceptable sources; iflscience is not one of them.

Phinds has given a pretty decent informal summary of what "wave-particle duality" does not mean and there's no point in further discussing the iflscience article, so this thread is closed.
