**Rydberg equation:**

$\overline{)\frac{\mathbf{1}}{\mathbf{\lambda}}{\mathbf{=}}{{\mathbf{R}}}_{{\mathbf{H}}}\mathbf{(}\frac{\mathbf{1}}{{{\mathbf{n}}^{\mathbf{2}}}_{\mathbf{final}}}\mathbf{-}\frac{\mathbf{1}}{{{\mathbf{n}}^{\mathbf{2}}}_{\mathbf{initial}}}\mathbf{)}}$

**Calculate n _{final}:**

λ = 2166 nm → convert to m

* 1 nm = 10 ^{-9} m*

An electron in the n=7 level of the hydrogen atom relaxes to a lower energy level, emitting light of 2166 nm.

What is the value of n for the level to which the electron relaxed?
