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