The maximum number of emission lines when the excited electron of an H atom in n=5 drops to the ground state?
15
10
20
5
As learnt in
Paschen , Bracket and Pfund Series spectrums -
Infrared Region
-
Each different transition of the electron results in a different emission line. So, as far the figure 5
The figure contains all possible transitions.
possible emission lines (max.) = 10
Option 1)
15
This solution is incorrect.
Option 2)
10
This solution is correct.
Option 3)
20
This solution is incorrect.
Option 4)
5
This solution is incorrect.
