One of the lines in the emission spectrum of Li^(2+) has the same wavelength as that of the 2nd line of Balmer series in hydrogen spectrum. The electronic transition corresponding to this line is:

One of the lines in the emission spectrum of Li^(2 +) has the same wavelength as that of the second line of Balmer series in hydrogen spectrum. The electronic transition correspnding to this line is.

Assertion: It is not essential that all the lines available in the emission spectrum will also be available in the absorption spectrum. Reason: The spectrum of hydrogen atom is only absorption spectrum.

One of the lines in the emission spectrum of Li^(2+) has the same wavelength as that of the 2nd line of Balmer series in hydrogen spectrum. The electronic transition corresponding to this line is n = 12 to n=x. Find the value of x.
