What happens if a lightwave and an orbiting electron collide - ClydeDavis - 01-22-2011

What happens if the photon energy is much greater than the difference between the final and initial energy state of the atom?
What happens to the photon once it has become absorbed by the atom?

Can i eyes register the change when a electron changes its orbital state? . e. g a flash of bright colour, for instance?
Does this partly explains how a laser works, for example?
Do atoms with extra photons jiggle about more?

An electron which is bound to an atom or a molecule can absorb a photon (a quantum of light energy) and jump to a higher energy state or out of the atom completely, creating an ion. This can happen only if the photon energy is the same as the difference between final and initial energy of the electron.
