Thank you for your help Vela, and patience. This helps my comprehension on the matter a lot!

As Eγ=hc/λ I take the inverse of the increasing factor, and in order to satisfy the square, this would also be squared, and multiplied with the corresponding wavelenghts, in order to get the values respective to oxygen! :)

4/3, so this is the factor we increase to get from C to O, would we then take the inverse of the wavelengths, that being 3/4? That can't be correct because it doesn't take into account the square function, so would I apply this to the inverse and multiply the wavelengths? I hope that's right..

Unconfidently I'll say a factor of 2..

Wavelength is inversely proportional to energy...Ok, so, as the atomic number of oxygen is higher, cleary more energy is released when the electron drops between shells. This would mean shorter wavelengths. As Z increases by 1/3 from carbon to oxygen, am I correct in assuming the wavelengths...

Sorry, my apologies, what I meant was the Z values are scaled up in squares...but I cannot visualise where I go from here with the data I have...

Hi Vela, appreciate your help. I have gotten much further with this now, just having slight difficulties with the following problem which asks to find the corresponding wavelengths from hydrogen like oxygen. Having attained some advice I have been told all that is needed is to scale up the Z...

Hi, unfortunately not, I'm a little closer but still do not fully understand how to fulfill the problem...

Apologies, I've read into the selection rules more in depth than just as is shown on wikipedia, but still having some difficulties. Does this then mean I have to calculate the total angular momentum between each possible transition?:rolleyes:

A side question here, If I have an atom that is not hydrogenic, how do I find this wavelength? Thanks

Thanks for your response SpectraCat. How would I proceed if this is the only information I am given in a question; Look up the constants delta and beta at carbon 2p - 1s transition energy for tungsten and carbon. Answer the following questions, which all refer to this energy... I believe I...

How do I find the energy difference between 1s and 2p, in a carbon atom? I'm right in assuming this is a constant value, and yet I cannot find the answer anywhere..? Thanks

Homework Statement Having problems with this subject. Given hydrogenic carbon, with binding energies of 490 eV (1s) 857.50 eV (2p) 925.54 eV (3p) 949.36 eV (4p). Find wavelengths of all lines due to electric dipole transitions between the levels. State which you expect to be strongest...

Hiya, been given this question which I am having problems with. Semi conductor quantum well structure contains a 100A thick layer of GaAs between thick AlGaAs layers. Find the band gap for the structure, where GaAs has the following parameters; conduction band effective mass 0.067 me, heavy...
