Sodium Vapor Lamps (1.19 hw) [ENDORSED]

Sodium vapor lamps, used for public lighting, emit yellow light of wavelength 589nm. How much energy is emitted by: a) an excited sodium atom when it generates a photon b) 5.00 mg of sodium atoms emitting light at this wavelength c) 1.00 mol of sodium atoms emitting light at this wavelength Please h...

Re: For H, what is common to lines within an emission spectr

Spectral lines imply the different energy levels for electrons in atoms. Lines that have a common n(sub1) are grouped into series: n=1 is Lyman, n=2 is Balmer, n=3 is Paschen, n=4 is Brackett, n=5 is Pfund.
