. Number of spectral lines in the resulting spectrum emitted will be
Text Solution
Verified by ExpertsThe correct answer is:
C
Energy of the photon, 
After absorbing a photon of energy 12. 
the electron will reach to third excited state of energy −0.85 eV, since energy difference corresponding to
and n 
4 is 12.75 eV
Number of spectral lines emitted
