Hydrogen atoms are de-excited from N she...

Hydrogen atoms are de-excited from N shell. Illustrate the spectral lines obtained in the emission.

Text Solution

Verified by Experts

Number of spectral lines =
`Sigma(n_(2)-n_(1))=Sigma(4-1)=Sigma3=3+2+1=6`.
Six spectral lines are obtained : 3 Lyman lines in UV, 2 Balmer lines in visible and 1 Paschen line in IR region.
