Light from a fluorescent lamp isobserved through a cloud of cool nitrogen gas. Again, two studentsare having a discussion about the kind of spectra that they wouldsee.
Student 1: We wouldsee absorption line spectra and the missing lines would correspondto the light from the fluorescent lamp.
Student 2: Idisagree. We would see an emission line spectrum corresponding tonitrogen. This would happen because the nitrogen gas would absorbsome energy from the fluorescent lamp and would reemit this energywhich would result in an emission line spectrum.
**** Which student, if any, do you agree with and why?
