bits and pieces of info are scattered in this post here, i'll sum up whati know.
1. photons can NOT jump up a few levels then use another photon to jump up another few levels, it does not work that way. the electron will only jump up the number of energy levels that the first photon hitting it can provide then fall back down before another photon hits it. example, if it takes 5eV to jump to the second level and 7eV to the third level and you shoot photons with an energy of 6eV into the sample, any electrons hit will jump to the second level and gain 1eV in heat then drop down a level. no electrons will jump to the third level.
2. all particles will absorb certain frequencies of light if that light has the exact energy needed to jump up a number of energy levels then emit that same frequency of light in all directions, this is how light filters work. a beam of light at x frequency will be absorbed by the substance, the electrons will go up a level then back down and the same frequency of light will be emitted but in all directions. when passing light through a sample then observing which frequencies of light are absorbed, absorbed frequencies of light appear as black lines when the filtered light is split into a spectrum.
3. the opposite of the process in number 2, if you put a very large voltage through a gas sample of something, the elctrons will jump up and down levels and emit only certain frequencies of light. jumping from level 3 to 1 will have a certain frequency of light, 2 to 1 will have a different frequency and 3 to 2 will have a different frequency.
4. the 3 series that i know:
Lyman series - when electrons fall to the first electron orbital
Balmer series - when electrons fall to the second electron orbital
Paschen series - when electrons fall to the third electron orbital
5. at a certain level of energy of light, electrons in a sample, when hit by a high energy photon, will simply leave. in hydrogen, this value is 13.6eV.
