Briefly explain why spectral lines are useful in determining the temperature of their source

What will be an ideal response?


Different ionization states of the same element have different sets of spectral lines. Thus, we can identify the ionization state, which tells us about the temperature because higher temperatures are required to reach higher ionization states.
