If an electron is capable of absorbing a photon that has a very specific frequency then it is also capable of emitting a photon that has that same very specific frequency. * *> The one used as a standard uses the cesium-133 transition between two > specific energy levels that emit photons with frequency 9,192,631,770 Hz. * > *That number is associated with the amount of energy an electron can have when it is very near a cesium 133 nucleus, and an electron has no internal structure as far as we know. When such an electron decays from a higher energy state to a lower one it emits a photon of light that has that frequency and the electron falls to a lower energy level. And such a low energy electron is equally capable of absorbing a photon with frequency 9,192,631,770 Hz and becoming a high energy electron. * *John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* 3s( > > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
