E=R(1/n-1/n)?
I'm confused on how exactly Borh's equation is turned into E=R(1/n-1/n) when finding the difference in energy level?

Re: E=R(1/n-1/n)?
ΔE=Ef-Ei
En= -hR/n^2
ΔE= -hR/nf^2 - (-hR/ni^2)
ΔE= hR/ni^2 - hR/nf^2
V=R(1/ni^2 - 1/nf^2)
ΔE/h= R(1/ni^2 - 1/nf^2)
ΔE=hR(1/ni^2 - 1/nf^2)
ΔE=hR/ni^2 - hR/nf^2
En= -hR/n^2
ΔE= -hR/nf^2 - (-hR/ni^2)
ΔE= hR/ni^2 - hR/nf^2
V=R(1/ni^2 - 1/nf^2)
ΔE/h= R(1/ni^2 - 1/nf^2)
ΔE=hR(1/ni^2 - 1/nf^2)
ΔE=hR/ni^2 - hR/nf^2

Re: E=R(1/n-1/n)?
Are we supposed to use E= R(1/n-1/n) or E= hR/n^2 when finding the difference in energy levels?

Re: E=R(1/n-1/n)?
When given two energy levels (n1,n2) or a beginning and ending energy state you can use the E=R(1/n-1/n). The other formula, E=-R(h/n^2) is used to find the energy of an electron in the nth state of a hydrogen atom specifically

Re: E=R(1/n-1/n)?
I am not 100% sure, but I think the equation R(1/n^2-1/n^2) is used to find the frequency, where the first one is initial and the second one is final because when deriving it you would get a negative final plus a positive initial, therefore it can switch places to make it a little simpler. (This was in my notes from discussion)

E=R(1/n2^2-1/n1^2) is the equation to specifically find the change in energy. The E= -hR/n^2 is for one specific energy level

Re: E=R(1/n-1/n)?
If a problem states energy was emitted would the final answer be negative and if the problem asks energy was absorbed would the final answer be positive?
