Answer» `10` different spectral lines are observed `rArr Deltan=3` HENCE MAXIMUM number of spectral line observed `=(3(3+1))/(2)=6`.  (C) number of lines belonging to the Balmer series `=3(5 rarr2, 4rarr2, 3 rarr 2)` as shown in figure. Number of lines belonging to Paschen series `=2(5 rarr 3, 4 rarr 3)`. |
