For the Balmer series in the spectrum oF H atom, `vec(v)=R_(H){(1)/(n_(1)^(2))-(1)/(n_(2)^(2))}` the correct statement among (I) to (IV) are:
(I) As wavelength decreases, the lines in the series converage
(II) The integer `n_(1)` is eqaual to 2.
(III) The lines oF longest wavelength corresponds to `n_(2)=3`
(IV) The ionization energy oF hydrogen can be calculated From wave number oF these lines:
