### Atomic Spectra Pre-Assessment #12

What is the experimental setup for a spectroscopic experiment?

Atomic spectra come from absorbing and re-emitting of light energy, so it can't be B or D. It also can't be C because it should have nothing to do with the speed of the hydrogen atoms, it should have to do with the energy levels of the electrons. So it's A.

Not sure the exact setup but in lecture Professor Lavelle spoke of pointing a light source at whatever metal you are testing. If electrons are ejected from that metal then the light source has a high enough frequency/energy to raise the electron to its second energy level (n=2).
