Emission transitions in the Paschen seri...

Emission transitions in the Paschen series end at orbit n=3 and start from orbit n and can be represented as `v=3.29 xx 10^(15)`(H z) `[1 / 3^2-1/ n^2]` : Calculate the yalue of 'n' if the transition is observed at 1285nm. Find the region of the spectrum.
