What is the main difference between an emission and an absorption spectrum?

• Emission spectra show dark lines, absorption spectra show bright lines

• Absorption spectra show dark lines, emission spectra show bright lines

• Both show bright lines

• Both show dark lines

How can star spectra help determine the temperature of a star?

• By the intensity of the blue color
