About electron radiation frequency in Heisenberg's 1925 paper
In Heisenberg's 1925 article Quantum Theoretical Interpretation of Kinematic and Mechanical Relations, one of the first things he establishes are the form of the frequency functions in (what I assume ...

How could I calculate the strength of an electromagnetic field sufficient enough to generate plasma in low pressure argon gas?
For context, I wish to create a plasma toroid in a glass sphere of 25 Torr Argon gas like in the photo below; there are multiple examples of how to do this online using a class E oscillator ...

Maximum energy emitted by quantum particle in infinite potential well
I've come across an interesting problem in QM which I can easily solve using classical radiation theory, but I can't seem to grasp how this theory extends to the quantum realm. The problem statement ...

Is there a limit to the number of observers to a wireless broadcast due to quantum mechanics?
My question seems obvious but nobody is talking about it. The way I understand it, an electromagnetic wave collapses to a particle when observed. This goes for electrons and photons but I imagine the ...

Analogy between the Electromagnetic Field and the Schrodinger Equation
In this answer my2cts says "The electromagnetic field is to photons what the Schrödinger or Klein-Gordon wave function is to electrons." Could someone expand on this further? Is this just a ...

Problem with Bohr Frequency in Quantized Radiation - Matter interaction
Consider an Hydrogenic Atom (no relativistic corrections and no reduced-mass effects) in a Quantized Electromagnetic Pulse given by the wave-packet:
$$
\underline{\hat{A}}(\underline{\hat{r}}, t) = \...

On a tinted (reflective) window, why do I need to look from up close to see inside?
I've noticed that on a really tinted window, when looking from farther (and even pretty close just not touching the window), you cannot look inside, but when you put your head so close to the window, ...

Can you have diffraction without a slit, simply by reducing the size of light source?
Since the diffraction pattern only depends on the width of the slit and the wavelength of light, could we see a diffraction pattern if we use an extremely small (to the order of micrometers) light ...

Which factors determines whether a photon is absorbed? [duplicate]
After some research, I figured out that all EM waves/photons are absorbed by atoms by exciting an electron from an orbital to an other. However, atoms emit only certain EM waves with specific ...

Electromagnetic field affect on hydrogen atom energy levels
If hydrogen atom is in the ground energy state it must be hitted by photon with energy higher than electron proton energy binding which is 13,6 eV according quantum mechanics. Proton have positive ...

Tunnel ionisation and how to interpret changes in potential curve
I have been doing some literature review on species ionisation to understand a particular mechanism that occurs when a high-intensity femtosecond laser interacts with molecular nitrogen to produce ...

What happens when a photon interacts with a free electron?
When an electromagnetic wave interacts with a free electron the electron starts to oscillate in the direction perpendicular to the propagation of the wave meanwhile when a photon interacts with a free ...

On sum of amplitudes in Wave Mechanics
Consider Schroedinger equation, which I write in the form $$ (\mathscr{L}+V)\psi=0$$where $\mathscr{L}$ is the kinetic and time-derivative operator. Now, imagine I have two point sources 1,2 with ...

Standing Waves are formed by an Electromagnetic radiation inside a cavity
While seeing the derivations of the Rayleigh Jeans law and the Planck's Law for a Blackbody Radiation, I came across a fact that they assumed that Electromagnetic Radiation inside a cavity would form ...

How to define relevant emission spectrum lines? [closed]
I am building a tool which extracts the elemental composition of a light source using its emission spectrum. Therefor, I'm currently writing down the emission spectra of individual elements, but I'm ...
