Question
Hydrogen atom in ground state is excited by a monochromatic radiation of λ = 975
. Number ofspectral lines in the resulting spectrum emitted will be
. Number ofspectral lines in the resulting spectrum emitted will beOptions
A.3
B.2
C.6
D.10
Solution
Energy incident = 
eV
= 12.75 eV
The Hydrogen atom will be excited to n = 4
Number of spectral lines =
= 6
eV= 12.75 eV
The Hydrogen atom will be excited to n = 4
Number of spectral lines =
= 6Create a free account to view solution
