Question
A photon of energy 12.09 eV is completely absorbed by a hydrogen atom initially in the ground state. The quantum number of the excited state is
Options
A.4
B.5
C.3
D.2
Solution
Energy difference in hydrogen atom = 13.6 - 
= 12.09 ⇒ n2 ≈ 9 ⇒ n = 3
= 12.09 ⇒ n2 ≈ 9 ⇒ n = 3Create a free account to view solution
