Sodium vapor lamps, used for public lighting, emit yellow light of wavelength 589 nm. How much energy is emitted by an excited sodium atom when it generates a photon?

To solve this problem, you get the equation E = hc/ λ. This comes from both E = hv and c = vλ. For part a, you just plug in the values, with λ being 589*10^9m
