... On the other hand, there's probably not much utility in discussing photons of, say, a 14MHz signal, simply because the energy contained in one quantum at that frequency is so small that you won't be able to detect it: a little less than 10^-26 joules per photon. At one photon per second, that's under 10^-26 watts, if you collect all the energy. At 50 ohms, that's less than a picovolt. Noise in a 1Hz bandwidth in a 50 ohm resistor at room temperature is about a thousand times that much. -- Yes, the energy is quantized. But the quanta are going to be _very_ difficult to distinguish. Cheers, Tom If there are, indeed, as many photons being emitted by the thin edge of the ribbon, as by the broad edges, what law/effect/affect is being demonstrated here? Or. why are the photons "drawn" to the thin edge with such magnitude of force? If this ribbon was white hot (even infrared) a meter would indicate more energy from the greatest surface area. Occams' razor is wrong, again? I have never read of the phenomenon you seem to be suggesting here ... Regards, JS |

Try the combination of all amplitudes and phases at a distance (pretty usual stuff already covered). Or. why are the photons "drawn" to the thin edge with such magnitude of force? What force? Give us a number, Tom did. If this ribbon was white hot (even infrared) a meter would indicate more energy from the greatest surface area. Occams' razor is wrong, again? I have never read of the phenomenon you seem to be suggesting here ... Consult Planck where it (predating the term photon) is summed up in two variables and one constant. 73's Richard Clark, KB7QHC |

Well, other than they are both text, both sent over the internet, both are smtp protocols, both are typed, both required the use of a computer, both were/are in english--well, 'ya know what I mean ... :-) Regards, JS |

Or. why are the photons "drawn" to the thin edge with such magnitude of force? The 14MHz photons are being emitted by the whole antenna, not by "broad edges" or "thin edges" as you suggest. You seem to be thinking of them as little tiny balls, or some such. That mental image just doesn't hold water. As I posted elsewhere in this thread, photons do not behave like billiard balls. They don't behave like anything you have encountered in the macro world we live in. There are some decent "modern physics for the masses" books that will explain to you some of the behaviour that you will probably think very strange, if you are thinking in terms of how the macro particles you're familiar with behave. Even particles like electrons, neutrons and protons don't behave like large spheres. They have distinct "wave- like" behaviour. As a start, it would probably help if you dropped "wave" and "photon" (particle) from your vocabulary when dealing with things like this and realize that the antenna emits a stream of quantized energy, with characteristics that can be described accurately without resorting to "particles" or "waves". If you had no idea what a passenger airplane was, but you were familiar with birds and busses, would you get into a discussion about the new thing being a bird and not a bus, or a bus and not a bird? Or would you realize that it has some characteristics of each, but is neither, and deserves a description all its own? Quantized radiation is rather like that. You will NOT describe it accurately as either "waves" or "particles" (in the macro sense). Cheers, Tom |
