We can determine the **wavelength, λ of the line corresponding to n=4 **in the

**Balmer series**using the

**Balmer Equation**shown below:

Recall that for the** ****Balmer series the final principal energy level n _{f} is always = 2.**

$\overline{)\frac{1}{\lambda}{=}{R}{\times}\left(\frac{1}{{{n}_{f}}^{2}}-\frac{{\displaystyle 1}}{{\displaystyle {{n}_{i}}^{2}}}\right)}$

*λ* = wavelength, m

R = 1.0974 x 10^{7}m^{-1} (Rydberg Constant) ***value can be found in textbooks or online *n

_{i}= initial principal energy level

**n**

_{f}= final principal energy level = 2 for Balmer Series###### Problem Details
