O lepton O hadron O boson O antiparticle 2 3 4 5 6 7 8 9 10How do the dark lines of an atom's absorption spectrum relate to the bright lines of its emission spectrum? O The bright lines are at the same energies as the dark lines. O The dark lines are at higher energies than the bright lines. O You cannot relate the two types of spectra. O The bright lines are at higher energies than the dark lines. 2 3 4 5 6 7 8 9Which device depends on the photoelectric effect?
