Chem 110 lab help. Please help me answer these questions?

We where doing a spectroscopy lab last week and I have to answer some questions at the end. here are some questions I need help on.

1) Could you use an emission spectrum other than that of mercury to calibrate your spectroscope? explain

2) Why will the flame test for sodium ion result in a yellow flame, even though green and orange lines appear in the sodium ion emission spectrum?

3) If you could observe and ABSORPTION (not emission) spectrum of hydrogen,What would it look like?

4)When you observe the emitted light of metal Ion solutions, how do know the resulting spectra comes from the cation such as sodium ion, and not the anion, such as chloride ion? Describe an experiment you could perform to verify results.
