How to absorb a characteristic line in a spectrum
I have an x-ray tube. When I see the spectrum, I notice the characteristic lines of the anode. What do I have to do if I want to absorb a characteristic line?
I have thought that I can add a filter. ...

If photon energies are continuous and atomic energy levels are discrete, how can atoms absorb photons?
If photon energies are continuous and atomic energy levels are discrete, how can atoms absorb photons? The probability of a photon having just the right amount of energy for an atomic transition is ...

What do we actually mean when we say that matter is a wave?
What do we actually mean when we say that matter is a wave?
What does the wavelength of this matter wave indicate?
The idea of a particle behaving like a wave is kinda incomprehensible to me.

Do electrons in multi-electron atoms really have definite angular momenta?
Since the mutual repulsion term between electrons orbiting the same nucleus does not commute with either electron's angular momentum operator (but only with their sum), I'd assume that the electrons ...

What keeps particles in an atom from flying away or falling into the nucleus?
In atoms, what force or charge, etc. keeps particles from flying away or into their nucleus? is there a kind of weak-force at work on the atomic scale?
Note I am aware the particle positions are ...

Disproving a refutation of quantum mechanics (QM) via a calculation of the ground state of the helium atom
This website http://www7b.biglobe.ne.jp/~kcy05t/ appears to refute Quantum mechanics using some proof.
An important paper involved is this 'Calculation of Helium Ground State Energy by Bohr's ...

Is the photon energy required to cause an atomic transition $\Delta E+\Delta KE$, where $\Delta E$ is the “transition energy”?
An atom "at rest" can absorb a photon, and while some of this energy goes into increasing the energy level of the electron, momentum must be conserved, and so some energy must also increase the ...

Where do electrons get the energy to remain in orbit? [duplicate]
As we know electrons continuously revolve around the nuclus without falling in it at a high velocity beating it's force of attraction. My question is where do electrons get energy to revolve around ...

Explanation of energy levels in molecules, atoms, nuclei and their relationship
Why are the energy levels of molecules, the atoms that form them and the nuclei inside the atoms considered separately? Or phrased in a different way- what is it that makes their energy levels so ...
