Consider this. Waves and photons exist in visible light at any frequency. If the frequency is lowered below the visible spectrum all the way down to say, 1 MHz, at what point do the photons disappear? Or do they just get weak? |

Photons exist in visible light at MANY frequencies where such frequencies are generated by the transition of an electron to a lower energy orbit around an atom. What is the mechanism by which your photons at 1 MHz are created? |

What is the mechanism by which your photons at 1 MHz are created? Photons are not "created" as such. They (and waves) are merely different aspects of the same phenomenon. What you look for is what you will observe. It may well be that, because the photon energy at 1 MHz is minuscule, there is no practical way of observing them. But that doesn't mean they don't exist. |

What is the mechanism by which your photons at 1 MHz are created? I am not arguing with you Gareth. I think I am agreeing. I am lacking in theory. I freely admit that. I am going on common sense. Photons, light move through our atmosphere in a straight line unless reflected by air temperature layers or mirrors. EM radiation moves through our atmosphere in a more complex way. It is reflected by our ionosphere or might be absorbed by something. My receiving antenna is a shielded loop. The antenna itself is copper and then it is covered with an aluminium shield that is grounded to stop the electrical part of the EM transmission. This guarantees that I will not receive any light/photons from my antenna. It simply makes no sense to me that I am receiving any information via light. I would love to hear a simple explanation that explains to me why my inverted V on 75 meters is emitting photons/light when I put 1500 watts of power to it. I remember years ago in physics class that this discussion came up in my college classroom. The professor told us that EM transmission was completely different than the transmission of light. It had occurred to me that if we built a transmitter on a frequency of visible light that somehow light would be emitted from the antenna. He said that there would be EM transmission but no light. I accepted his opinion because he knew far more than myself. I have accepted that explanation since 1968 when he was teaching that class. What I hear being said here is that EM transmission is composed of photons. I always thought of it as a simple electromagnetic wave, like what we use in transformers and radio communications every day. Again, what I hear being said here is that radio waves are just lower frequency light waves. Really? Not looking for a flame war, just a simple answer to my question. |

Yes, radio waves are just lower frequency light waves, and light waves are just higher frequency radio waves. And both have the properties of photons as well as the properties of waves. The important thing to realise is that photons don't have to be linked to light, despite their name, because the light-related name was just a historical accident of how they were discovered. The photons equivalent to lower frequency electromagnetic radiation such as radio waves can't be seen and get to and from antennae even if they are effectively screened from the light. -- Roger Hayter |

Thanks for that polite response. I really could not ascertain an answer through all the static before. It appears my professor was mistaken, or perhaps he was telling us what was known at that time. Now what ham radio needs is a completely new type of communication. I am thinking of those twin particles that react to one another regardless of distance and without the delay of distance. I think this was demonstrated very well on Star Trek. They can talk across light years instantly. To bad Gene is dead. He could have helped us all out with just how to do this. It was in all the scripts, it must be true. It is my mythology so don't be making fun of it. :-) |

But anyone who knows is welcom to contradict me on this! It is known as Quantum entanglement communication. in theory it works (and doesn't which is very quantum) it is similar to teleportation where a particle has been teleported in as much as the defining state information from the particle has been sent to another particle. It is doubtful whether either can be brought into the macro world so it could be a long time before anyone gets to say "beam me up Scotty". The idea behind Quantum entanglement communication is that you create quantum twin particles that are entangled and manipulate one to create instant reaction with the other. "Spooky action at a distance"-Einstien. And as soon as someone suggests it someone says it is not possible. There is a No-Communication hypothesis that prevents the sending of information via a quantum entangled state. My head hurts now. Andy |
