### Energy vs wavelength relation is given by, $E\left(eV\right)=\frac{1241}{nm}$. Energy of H-atom in the ground state is -13.6eV as form the relation $E\left(eV\right)=-13.6\frac{{Z}_{eff}^{2}}{{n}^{2}}\left(eV\right)$. Find that in which transition on hydrogen atom is the wavelength 486.1 nm produced? To which seriesdoes it belong ?

### Why can one observe an electronic transition of the 3s state to the 3p state in the emission spectrum of the nitrogen atom, but not in its absorption spectrum?I know that the selection rules technically don't forbid either one since $\mathrm{\Delta }\ell =±1$ is permitted.

### I need to be able to convert an arbitrary emission spectrum in the visible spectrum range (i.e. for every wavelength between 380 and 780, I have a number between 0 and 1 that represents the "intensity" or dominance of that wavelength), and I need to be able to map any given spectrum into a particular color space (for now I need RGB or CIE-XYZ). Is it possible?For the spectrum say I have the emission spectrum of a white light, then every wavelength in the spectrum will have an intensity of 1, whereas for a green-bluish light I'd have most of the wavelengths between 500 and 550 with an intensity close to 1, with other wavelengths gradually dropping in intensity. So the first spectrum should be converted to pure white whereas the other one would be converted to a green-bluish color in any color space.Is there a way to do this?

### For the hydrogen atom, the Balmer Series is the series of line spectra produced when an election falls from any higher energy level and has n=2 as its final energy state. The longest wavelength is the Balmer Series is 656.7 nm. what was the initial principal energy level (n) associated with this photon.Will the energy value in the trasnistion be the geatest or smalles in the entie Balmer Series?

### I learnt that in astrophysical spectroscopy, the emission spectrum of distant stars is used to determine what they're made of. So why is it that our own Sun is emitting the whole spectrum ?

### Calculate the two longest wavelength of the Balmer series of triply ionized berillium (Z=4)

### When light hits an atom (I will use a carbon atom for simplicity), if it is not in the absorption and/or emission spectrum of carbon, it will simply pass through without interacting with the atom. Whereas if it is in the absorption or emission spectrum it will be absorbed and either re-emitted or it will decay to become thermal energy.However, if there are a lot of (carbon)atoms in close proximity (like in a block of coal), the light will (obviously) not pass through it no matter where it is on the visible spectrum. Why does this happen?

### The wavelength of emitted radiation when an electron jumps orbits in the Bohr atomic model is given by1/$\lambda$ = ${R}_{H}$ ($\frac{1}{{n}_{f}^{2}}$ - $\frac{1}{{n}_{i}^{2}}$) ${Z}^{2}$But that of X-Ray emission is given by1/$\lambda$ = $1.1×{10}^{7}$ ($\frac{1}{{n}_{f}^{2}}$ - $\frac{1}{{n}_{i}^{2}}$) $\left(Z-1{\right)}^{2}$Why is there a difference? Why aren't X-Rays treated like any other emissions?

### From my quick investigation, the spectrum is based on the Rydberg formula, and with a small change, would lead to$\frac{1}{{\lambda }_{\mu }}=\frac{{m}_{\mu }}{{m}_{e}}\left(R\left(\frac{1}{{n}_{1}^{2}}-\frac{1}{{n}_{2}^{2}}\right)\right)$where ${m}_{\mu }$ is the mass of a muon.So, taking hydrogen as an example, we would observe similar bands, shifted into the x-ray/gamma range.Is this correct?

The majority of atomic physics questions and solutions that you will find might not deal with your subject directly since the atomic physics equations may not be suitable for your discipline. Likewise, some answers that you will find provided will be related to the lab reports and specific experiments. You can also approach Balmer series equation to determine the spectral line emissions as you focus on the hydrogen atoms. Exploring various atomic physics solutions, make sure that you provide an explanatory paragraph that will explain why you have chosen a certain methodology and what scientific objectives you have set to choose.
