Hey Guys,
i'm a first year astrophysics student and i got given this question to answer in a practical report:
Examine the spectrum of the planetary nebula derived from the diffraction grating. You will produce a colour rendering of the spectrum together with a graphical representation of intensity versus pixel number.
The pixel number scale can be replaced by a wavelength scale. Given that some of the bright emission lines are due to excited hydrogen and oxygen gas, determine a conversion between pixel number and wavelength. (Draw a graph showing pixel number on the x-axis and wavelength on the y-axis. The graph should be linear).
now i have a pixel vs intensity graph which appears to have three sharp peaks. I'm not quite sure on what I'm supposed to go from here.
thanks for your responses :)
