ok so i know whenever a photon is absorbed it will jump up a energy level and when it is emmited it releases energy. but my question is, for example, if k=1 (fundamental state) in a hydrogen atom and they give you the given wavelength of the photon, you solve it and you get n=2 would the photons absorb or emit? im just confused because at first i thought it would absorb, because it is a greater number but then i used the equation -13.6/n^2 and got me confused because k= -13.6 and n= -3.4 and i thought that the electron with the greater negative number is "stronger" because it attracts more, and i thought that for a photon to absorb it had to have "at least" as much energy as the electron it hits. So would it emit or absorb? do i have the wrong idea of whats going on? someone help please and explain to me.

thank you :)

2. Relevant equations

1/lambda= r(1/k^2-1/n^2)

hf= hc/lambda= energy of transition= energy of photon
