Please don't tell me what I am assuming because you are invariably wrong. As I (and Richard Feynman) have told you before, the fields emitted by electrons consist of photons. Electrons escaping a transmitting antenna are a non-coherent corona discharge. Photons escaping a transmitting antenna are coherent RF energy. "Feynman has been called the "Great Explainer".[23] He gained a reputation for taking great care when giving explanations to his students and for making it a moral duty to make the topic accessible. His guiding principle was that if a topic could not be explained in a freshman lecture, it was not yet fully understood". Back in the early 20th century when spark gap transmitters were being used, the spark gap function, like lightning, generated non-coherent photons which filled the RF spectrum. It were the damped waves. http://en.wikipedia.org/wiki/File:Ondes_amorties.jpg For Planck and Einstein that wave packets were the portion of energy. The name photon have many definitions. Nowadays, a CW signal is mostly coherent with a small amount of non-coherence associated with the transient rise and fall times. Are in CW a photons? S* |
