The reference lines are sharp and the real emission lines appear to be not so sharp. The reason for the
broadening is the resolution limits of the spectrometer.
You can use the reference lines to identify elements such as mercury in lamps and metallic elements in
flame tests.
Neon emission lines are closely packed in the yellow and red end of the spectrum. This is why traditional
neon signs have a warm red glow. Different gases produce different colors, so the blue shield is not neon.
