Figure P29.8 is an energylevel diagram for a simple atom. What wavelengths appear in the atom's

(a) emission spectrum and

(b) absorption spectrum?

An electron with \(2.0 \mathrm{eV}\) of \(n=3 \longrightarrow E_{3}=4.0 \mathrm{eV}\)

\(n=2 \longrightarrow E_{2}=1.5 \mathrm{eV}\)

\(n=1 \longrightarrow E_{1}=0.0 \mathrm{eV}\)
