This thread is related to another question that I have been pondering. In most objects that we experience on a daily basis (a green shirt for example), we know that most of the frequencies of light striking the object are absorbed. I simply can't believe that the atoms in the shirt have enough possible electron energy levels that would allow for so many frequencies to be absorbed. (plus they would just be re-emitted when the electrons decay back to ground state, with no net effect). Does this mean that there is absorbtion that takes place that simply shakes electrons without making them jump from one energy level to the next, thus absorbing light without re-emittting. Can this actually happen? Once again, thanks in advance for any help in the matter.
