Probable an impurity; the color of selenium in flame test is blue.
A fluorescent lamp contain mercury so the identities of spectrum are normal.
Because the band is broken by colorless gaps
The two types of spectrum are continuous spectrum, which shows a continuous range of colors with no gaps, and line spectrum, which consists of distinct lines of color separated by gaps.
In case of continuous spectrum we have all sorts of frequencies. This ensures that probability of transfer of electrons at various energy levels are equally available. But in case of line spectrum it is some how a characteristic which is restrained with the transfer of electrons in specified energy levels.
The line spectrum is usually used to sort out the atomic fingerprint as the gas emit light at very specific frequencies when exposed to the electromagnetic waves. The electromagnetic waves are usually displayed in form of the spectral lines.
The color of a mercury spectrum line with a wavelength of 576.96 nanometers is green.
Wavelengths of absorbed or emitted photons Every line in a line spectrum is caused by a transition, from one quantum state to another quantum state, involving electrons.
Absorption of energy at atom energy levels cause the line spectrum.

Many people get this 'green line' because they only brush the upper part of their teeth. If they continue to do this for a month or so, they plauge will build up so much it will form a 'green line'.
I'm curious about what you're seeing. Is it a metallic type green line? Not always in the same position. Moving around and can take any shape?
No, an absorption spectrum and a bright line spectrum are not the same. An absorption spectrum is produced when light is absorbed by atoms or molecules, showing dark lines at specific wavelengths. On the other hand, a bright line spectrum is produced when atoms or molecules emit light at specific wavelengths, creating bright lines in the spectrum.
dark-line spectrum...
the line spectrum of the hydrogen spectrum indicates that only certain energies are allowed for the electron of the hydrogen atom. In other words, the energy of the electron in the hydrogen atom is quantized.
A dark line found in a spectrum is called an absorption line. Absorption lines are created when atoms or molecules absorb specific wavelengths of light, resulting in dark lines in the spectrum where that light is missing.
A bright line spectrum refers to the pattern of distinct and bright lines of different colors that are produced when an element is excited and emits light. Each element has a unique bright line spectrum that can be used to identify the element through spectroscopy.
