Question

Which of the following statements about how light can interact with atoms is correct? (Check all that are correct)

		The photons most likely to ionize atoms have the longest wavelengths
		An atom can most easily absorb a photon with an energy that is equal to the difference in energy of two electron states.
		The frequencies of the spectral lines produced by an excited atom give the energies of individual electron states.
		The frequencies of bright lines produced by excited atoms match the frequencies where cooler atoms will most efficiently absorb light.
