- No. of spectral lines: The number of spectral lines obtained due to the transition of electrons from nth orbit to lower orbit is given by
\(N= {n(n-1) \over 2}\)
where N is the number of transitions and n is the orbit number.
Given that transition is from n = 4 to n = 1 (ground state). So transition spectral lines
\(N= {n(n-1) \over 2}\)
\(N= {4(4-1) \over 2} = 6\)
So the correct answer is option 3.
