We can determine the smallest wavelength, λmin in the Balmer series using the Balmer Equation shown below:
λmin = wavelength, m at the highest initial principal energy level: ↑ni ↓λ
R = 1.0974 x 107m-1 (Rydberg Constant) **value can be found in textbooks or online
ni = initial principal energy level
nf = final principal energy level = 2 for Balmer Series
Recall that for the Balmer series the final principal energy level nf is always = 2.
The smallest wavelength, λmin will be the minimum wavelength corresponding to the highest initial energy level, ni possible or approaching infinity, ∞ (a symbol used to denote a super high number) for a Hydrogen atom.
Recall that the highest transition releases the highest energy, E.
Energy, E is inversely proportional to the wavelength, λ: ↑E, ↑ni, ↓λ
