Emitting Photon and Energy Change

Discussion Overview

The discussion revolves around the behavior of electrons in quantum mechanics, specifically regarding the absorption and emission of energy, and the uncertainty surrounding the timing and location of an electron's transition between energy levels. Participants explore whether this phenomenon is considered a problem in physics and the implications of statistical behavior in quantum mechanics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions the interpretation of a statement from a book regarding the unpredictability of when and where an electron will transition to a lower energy level after absorbing energy.
  • Another participant suggests that the behavior of electrons is governed by statistical behavior, indicating that individual cases cannot be predicted, which may not constitute a problem in the traditional sense.
  • A participant connects the discussion to the uncertainty principle, suggesting that the statistical nature of quantum behavior may be related to this principle.
  • Some participants assert that spontaneous emission is a probabilistic process and that no observational evidence contradicts this aspect of quantum theory, implying that it is not a problem in physics.
  • One participant expresses a realization that their classical thinking may not apply to this quantum scenario, acknowledging the lack of a definitive answer.
  • References to external resources, such as a Wikipedia article on spontaneous emission, are provided for further exploration of the topic.

Areas of Agreement / Disagreement

Participants generally agree that the behavior of electrons in this context is probabilistic and governed by statistical mechanics. However, there is no consensus on whether this behavior constitutes a problem in physics, as some view it as a non-issue while others seek deeper understanding.

Contextual Notes

The discussion highlights the complexity of quantum mechanics and the challenges of interpreting probabilistic events. There are indications of varying levels of understanding among participants regarding the mathematical aspects of the topic.

I know that my title is not very suitable for this question, but I couldn't find right words to describe the situation.I read a book called '101 Quantum Questions ' and there writer states that when electron absorbs energy and goes higher energy level, we don't know when and where it will come to lower energy level.

1-Is this true ? (Am I interpreted this in a right way ? )
2-Is this problem solved ?
3-If its solved any references, If its not any ideas,referances about this issue so that I can search more deeply ?

Thanks

I'm not sure everyone would call this a problem. Much quantum behavior is governed by statistical behavior and cannot be predicted in individual cases. This is one of those.

I see...the book kind of represented in that way, maybe its about uncertanity principle ? But in other aspects make sense that its statistical and not a problem.

In physics a theory gets problems is it contradicts observational facts, but that's not the case here. Spontaneous emission is a probabilistic process, and no observation has disproven this consequence of QT. So there's no problem.

Make sense, I thought in a classical way that there must a certain answer to this problem but of course there's not..
