Which of the following colors would appear as a bright band in an emission spectrum of a yellow sodium vapor lamp?
The answer is:
Yellow, indicating a greater wavelength than ultraviolet light.
What I don't get is, why would yellow be emitted just because the sodium vapor is yellow? Doesn't the emission spectrum have to do with electron excitation and release of photons as the electrons move back down energy levels?
