Hello again, After asking for a better way to visualize electrons around a nucleus (and receiving one - thank you alxm), I am now left wondering about photons. How should I go about visualizing them? I have heard that they have a wavefunction, just like electrons do, but I would like to know more about the nature of that wavefunction. What does the wavefunction describe? What does the frequency describe? Does the wave fill a given area, or is it confined? Is there a good picture/diagram of how I should picture a photon?
