Question
Three photons coming from emission spectra of hydrogen sample are picked up. Their energies are 12.1eV, 10.2eV and 1.9eV. These photons must come from
Options
A. a single atom
B.two atoms
C.three atom
D.either two atoms or three atoms
Solution
12.1 = E(n = 3) − E (n = 1)
10.2 = E(n = 2) − E (n = 1)
1.9 = E(n = 3) − E (n = 2)
At least two atoms must be enveloped as there connot be two transition from same level from same atom.
