I Emitting Photon and Energy Change

[Arman777]

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

2-Is this problem solved ?

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.

You can get a general description of what affects the rate of emission, or relaxation time, by checking here:

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..

Thanks I looked at it, but math is complex for me now.
