The fine green lines are He reference lines. When the spectrometer is correctly calibrated; the lines match
the peaks.

The reference lines are sharp and the real emission lines appear to be not so sharp. The reason for the

The mercury lamp has lines in the red and infrared that are not mercury. This is due to other gases or
vapors in the lamp.
