1.	Hydrogen atoms are de-excited from N shell. Illustrate the spectral lines obtained in the emission.
Answer» Solution :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.
