Question

21) the ionisation potential of hydrogen atom is 13 6eV Find out
i)wavelength of H beta line in balmer seriesii)shortest wavelength
of lyman series

Ravi Gupta · Accepted Answer

(1) Balmer series , beta line:E = 13
6(122-142) = 13 60 25-0 0625=2
55 eV (2) Lyman series :for shortest wavelength :n2 = ∞E = 13
6(122-0) = 3 4 eV

21) the ionisation potential of hydrogen atom is 13.6eV.Find out i)wavelength of H beta line in balmer seriesii)shortest wavelength of lyman series.
