At which wavelengths do photons behave like X-ray?
Hard X-rays of wavelengths of about an angstrom are very different than regular lights in a way that they can’t be reflected or refracted, which means their refractive index is always close to 1 ...

Why does oxygen green (S1) emission in aurorae only occur at lower altitudes? [duplicate]
Aurorae have a red color at high altitudes caused by the excitation of atomic oxygen and the subsequent emission at about $630 \,\text{nm}$. This happens at high altitudes because at that height there ...

Energy level photon spectra for different atoms
I'm trying to determine the photon emission wavelength ranges for different atoms.
For hydrogen, it's super simple. We use the $$ E_n = -\frac{13.6}{n^2} $$
Then, if we want to see the wavelength of ...

Can the pilot wave theory explain why the circumference of an orbit has to be an integer multiple of the wavelength of the electron orbiting it?
Consider the atomic model proposed by Bohr. The velocity of an electron at any orbit is given by the following equation:
$$v= n \dfrac{h}{2\pi mr}$$
Now, this equation stems from the fact that, quote, ...

What are the advantages of radio spectroscopy? [closed]
What is the main purpose for radio spectroscopy? What information of the atomic structure of atoms can we gain from using radio frequency radiation rather than X-rays? Since the wavelength of radio ...

Does the Rydberg Formula work if the electron is going from lower to higher levels?
In all of the internet, all I see is examples about the Rydberg Formula about an electron going from higher levels to lower levels (like from $n=6$ to $n=3$ ), and it does make sense to be honest, ...

Why do lines become weaker in intensity as wavelength decreases?
In 1885 the first series was observed by Swedish school teacher Johann Jakob Balmer in the visible region of the hydrogen spectrum. This series is called the Balmer series. In Balmer series as the ...

How does wavelength affects uncertainty in momentum & position?
The objective is to locate a microscopic particle, in the presence of light of known wavelength and adjustable accordingly.
Brief on the setup.
Let there be a box containing the particles to be ...

Formula for wavelength emitted taking into account the quantum orbital number $l$
Rydberg's formula can be used to find the wavelength emitted due to an electron moving from one energy level $n_i$ to another one $n_f$. But when the Schrödinger's model of the atom is introduced we ...

Why is everything not invisible if 99% space is empty?
If every object is $99$% empty space, how is reflection possible? Why doesn't light just pass through?
Also light passes as a straight line, doesn't it? The wave nature doesn't say anything about its ...

How are characteristic and cut-off wavelength related to each other for a metal
Find the binding energy of an L electron in titanium if the wavelength difference between the first line of the K series and its short-wave cut-off is $\Delta \lambda=26 \;\text{pm}$.
Cut-off ...

Why do we rule out orbits with non-constructive interference for the atom? [duplicate]
It is said that de Broglie explained the quantization of Bohr's orbitals with the idea of the "matter wave" of the electron being forced to have orbits where it can interfere constructively ...

How do Fluorescent molecules emit light in a different wavelength than the one needed to excite them?
if it took a very certain amount of energy to excite an atom, how come when it de-excites it emits a photon of lower energy?
I know that's what scintillators do, I Just want to know the microscopic ...

The connection between the wavelength and the atom level
In my textbook it said the following:
Photons with wavelengths in the spectral range of $[94\mathrm{\ nm},104\mathrm{\ nm}]$, interact the hydrogen atom in the basic state. Photons having those ...
