Photons and electric fields?

  1. Jun 7, 2005 #1
    I have just read Feynman's QED book and am somewhat perplexed. I have read that photons are the culprit behind all electromagnetic phenomena. He explains electromagnetic radiation very well but I am lost when it comes to static fields. If two electrons are very close together (and repelling each other) are photons moving between them? If there are do they have wavelength or energy like photons in visible light? Please Help.

    These force mediators (the photons that the electrons exchange) are not on mass shell. They have a certain lifetime given by the Heisenberg's uncertainty principle. You see, these are only virtual quantas. The energy of these photons is also given by: E=hf=h(bar)omega
