An electron in H -atoms jumps from some higher level to 3rd energy level.If three spectral lines are possible for the transition, find the initial position of electron. |
Answer» Number of spectral lines `=((n_(2)- n_(1))(n_(2)-n_(1)+1))/(2)` ` implies 3 = ((n_(2)-3)(n_(2)-3+1))/(2)` `implies 6 = n_(2)^(2) - 5n_(2) + 6` ,brgt `implies n_(2)(n_(2)-5)=0` or `n_(2)= 0,n_(2)= 5` Since`n_(2)= 0`is not possible , hence `n_(2) = 5` |
