Quasars have what kind of spectral lines?
Quasars have all kinds of spectral lines namely more energetic ones which makes them the brightest objects in the night sky.
Is spectral interference more common in atomic emission spectroscopy or atomic absorption spectroscopy?
Spectral interference is more common in atomic emission spectroscopy due to overlapping spectral lines.
Will the wavelength of light from a second order spectrum be more accurate than the first order spectrum?
lines fainter in second orderand the lines are further apart :)
What happen to the spectrum of a star moving toward the earth away from the earth?
If a star is moving towards Earth. The light is seen as 'blue shifted'. As we look at our sun, on the colour spectrum, black lines appear. When looking at distant stars, we can tell if they are moving away from us (Red shift) or getting closer to us (Blue shift). This is because the black lines shift to the red or blue end of the spectrum depending on which direction the star is travelling.
Do noble gases form compounds with very bright colors?
The Noble Gases are colourless, monatomic elements. When they are excited electrically, each gas exhibits a distinctive set of spectral lines, characteristic of that element. Helium has five lines in the visible spectrum dominated by yellow; Neon has quite a few lines in the visible spectrum but appears orange to red; Argon also appears orange to red and Krypton appears more green and Xenon is blue - green.
Why would the star Sirius find that its spectral lines are blue shifted?
The spectral lines of Sirius are blueshifted because the star is moving more or less toward us.
Why are some spectral lines thicker than others?
In a spectral line from a rotating body such as a star, some of the matter emitting the line is moving toward you and has a part of its line shifted slightly to the bluer end of the spectrum, some is moving away and has a slight shift toward the red end, and the rest is moving more or less across your line of sight and the shift is normal.

Why does hydrogen spectrum contains 4 coloured lines why not 3 or 7?
In theory, hydrogen has infinitely many spectral lines. The "Balmer series" has four lines in the visible spectrum; additional lines are in the ultraviolet. Other "series" have other lines - it seems that all of them are either in the ultraviolet or infrared. For more information, read the Wikipedia article on "Hydrogen spectrum". The reason there are four VISIBLE lines is basically chance - an excited hydrogen atom emits light at certain frequencies (which can be calculated, see the article for more details); our eyes see a certain range of electromagnetic waves that happens to include four of those lines.
How does the spectral interference differ in inductively-coupled plasma mass spectrometry compared to flame?
Spectral interference occurs when spectral lines overlap. Inductively-coupled plasma mass spectrometry has more spectral interference as its higher energy allows more electron transitions.
What does zeeman effect mean?
The splitting of single spectral lines of an emission or absorption spectrum of a substance into three or more components when the substance is placed in a magnetic field. The effect occurs when several electron orbitals in the same shell, which normally have the same energy level, have different energies due to their different orientations in the magnetic field. A normal Zeeman effectis observed when a spectral line of an atom splits into three lines under a magnetic field. An anomalous Zeeman effectis observed if the spectral line splits into more than three lines. Astronomers can use the Zeeman effect to measure magnetic fields of stars. Compare Stark effect.

The lines at the ultraviolet end of the hydrogen spectrum are known as the lyman series wich electron transitions within an atom are responsible for these lines?
The series of lines in an emission spectrum caused by electrons falling from energy level 2 or higher (n=2 or more) back down to energy level 1 (n=1) is called the Lyman series. These emission lines are in the ultra-violet region of the spectrum.
What is it called when galaxies are moving toward each other?
There isn't a particular name, however, when they are moving towards us, their spectrum is shifted to the blue region. So they are referred to as blue shifted galaxies but that is only relative to ourselves. See related link for more information.
