B What is the relation between wavelength and orbital?

  1. Sep 17, 2017 #1
    I am in a chemistry class, and there was an in class example on how to do this type of problem, but then when I looked in the book, there wasn't an equation. the questions are related to what the wavelength will be when electrons are moving between orbitals.

    Could the Rydberg formula be what you're looking for?

    Alternatively, if you have an equation that gives the energies of the orbitals, you can get the same result by finding the difference in energies between the two orbitals, which gives the photon energy, then using Planck's famous formula E = hf.

    Did you copy the example from class? If so, please post it and we can try to figure out what's going on in the problem.

    Thanks for the help, it turned out the assigned reading didn't cover it, they had to edit the syllabus, it was rydberg's equation.
