Why do atoms emit discrete frequencies of light?

AI Thread Summary
Atoms emit discrete frequencies of light due to their quantized electronic energy levels, which dictate the specific positions of electrons. These energy levels arise from quantum mechanics, particularly illustrated by Niels Bohr's model of the hydrogen atom, which, despite being outdated, effectively introduces the concept of energy quantization. Different atoms possess unique sets of energy levels, leading to the emission of distinct light frequencies when electrons transition between these levels. Understanding these principles is essential for grasping atomic behavior and spectral lines. The study of these discrete energy states is fundamental in fields such as spectroscopy and quantum physics.

Why are electronic levels present for an atom? What is the need for differentiating energy levels?

What do you think?
 
I was taught that energy levels are used for differentiating the position of an electron in an atom. Why is that it needs to be specific levels?
 
I guess you are asking why different atoms have different discrete energy states and if so the best answer comes from quantum theory.It will help if you study Niels Bohr's analysis of the hydrogen atom.Try googling "Bohr atom".The analysis can be described as being obsolete but it is still widely studied because it introduces the concept of energy levels and it makes a good introduction to the subject.

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
