Sodium

Confidence: 100%. ?
Spectral lines of Sodium.I chose to photograph a high pressure sodium lamp to show the less intense lines clearly. Sodium usually looks more like the generated chart above, and its intense yellow lines are an unavoidable contaminant in some of the spectrum photos on this site.
