A sodium atom in one of the states

A sodium atom in one of the states labeled “Lowest excited levels”
in Fig. 39.19a remains in that state, on average, for 1.6 s
before it makes a transition to the ground level, emitting a photon
with wavelength 589.0 nm and energy 2.105 eV. What is the uncertainty
in energy of that excited state? What is the wavelength
spread of the corresponding spectral line?
