Derive from the Uncertainty Principle a formula for the relative spread of the spectral line that corresponds to the longest wavelength of the Lyman series.

Relevant equations

uncertainty principle:

?x?p??/2

planck constant

?=h/2pi

h=?p

Lyman series:

1/?=RH(1-1/n2)

?=hc/Ei-Ef

I'm not quite sure how to go about the problem. I have gathered some formulas I believe will help me out. If I substitute some of these formulas in to the uncertainty principle I get

?x?p?(hc/Ei-Ef)p/(4pi)

I'm not sure where to go from here. Any help would be greatly appreciated.
