), where RH is a constant and n1 and n2 are integers.
(i) As wave length decreases, the lines in the series converge
(ii) The integer n1 is equal to 2
(iii) The ionization energy of hydrogen can be calculated from the wave number of these lines
(iv) The line of longest wavelength corresponds to n2=3
