Homework Statement
For our investigation, we used a diffraction grating spectrometer to observe the emission spectrum of mercury.
We conducted the experiment in a pitch black room to avoid any unwanted light pollution, etc.
Whilst conducting the experiment we observed a number of 'faint' lines surrounding each of the brightest emission lines. For example, several faint blue spectral lines were observed surrounding the blue spectral line with the greatest luminosity. You can see these here: http://imgur.com/a/6KsOh
I was wondering if what we observed was perfectly normally, and if there is a name for it as well as a good explanation to include in my report.

The Attempt at a Solution
I have noticed that what we observed are somewhat similar to the following image of the Mercury emission spectra: https://i.stack.imgur.com/onjhd.png
There appears to be some sort of light with a lower luminosity in-between each of the bright spectral lines, especially the red. However, I don't know the meaning of this.
My Physics teacher is ill and has been on leave, and I have been unable to make contact with him. I asked the other physics teacher at my school and he was unable to explain our observations.
Any help would be much appreciated :) Thanks
