Finding Energy Level for H-Atom
Hi, I am not sure how to solve this problem. I tried using the wavelength value to find the energy of the photon emitted, but I am not sure where to go from there. Attached is question 1.15 from 6th edition.

Re: Finding Energy Level for H-Atom
For a line at 102.6nm, you convert into meters and then do following:
V=c/λ
=(3.00*10^8ms^-1)/102.6*10^9m= 2.922 * 10^15 s^-1
Then use Rydberg to find values for N :
V=R[(1/n1^2)-(1/n2^2)].
We know that hydrogen has n1= 1, so
1/n2^2= 1/1^2 - V/R
1/n2^2= 1 - ( 2.922 * 10^15 s^-1)/(3.29 * 10^15 s ^-1) = 0.112
n2^2= 9
n2= 3
Answer is 3

Re: Finding Energy Level for H-Atom
Does n1 mean energy level one, or only in the case for H-Atoms. I thought n1 was just notation for initial energy level.
