step 1: calculate the final state after excitation
wavelength = 92.27 nm
wavelength = 9.227*10^-8 m
Here photon will be captured and it will excite the atom
1/lambda = -R* (1/nf^2 - 1/ni^2)
R is Rydberg constant. R = 1.097*10^7
1/lambda = -R* (1/nf^2 - 1/ni^2)
1/9.227*10^-8 = - 1.097*10^7*(1/nf^2 - 1/1^2)
(1/nf^2 - 1/1^2) = -0.9879
1/nf^2 = 1.205*10^-2
nf^2 = 83
nf = 9
step 2: Now calculate the final state after emission
wavelength = 383.4 nm
wavelength = 3.834*10^-7 m
Here photon will be captured and it will excite the atom
1/lambda = R* (1/nf^2 - 1/ni^2)
R is Rydberg constant. R = 1.097*10^7
1/lambda = R* (1/nf^2 - 1/ni^2)
1/3.834*10^-7 = 1.097*10^7*(1/nf^2 - 1/9^2)
(1/nf^2 - 1/9^2) = 0.2378
1/nf^2 = 0.2501
nf^2 = 4
nf = 2
Answer: 2
