For Balmer series, shortest wavelength is when transition takes from n = 3 to n = 2.
Wavelength for transition is given by, $\frac{1}{\lambda }=\left(1.097×{10}^{7}\right)\left(\frac{1}{{n}_{1}^{2}}-\frac{1}{{n}_{2}^{2}}\right)$
Substituting values,
$\frac{1}{\lambda }=\left(1.097×{10}^{7}\right)\left(\frac{1}{{2}^{2}}-\frac{1}{{3}^{2}}\right)\phantom{\rule{0ex}{0ex}}\lambda =6.56×{10}^{-7}m=656nm$
Since 1000 nm > 656 nm, hence, it belongs to Balmer series.
