Photons?

Planck's hv gives a fixed, particular energy for each photon; so how many complete cycles does the photon have within its amplitude envelope? For those who maintain that RF radiation from antennae is composed of photons, where does each photon end and the next one begin? What experimental evidence is there that RF photons exist (it is easy to show the existence of continuous waves, of course) These are pretty fundamental questions raised from the claim of photons and perhaps the inability of the photonists to answer them is indicative of their weak and uncertain knoweldge of the subject area? You can apply all those arguments to a torch (flashlight), and they will be equally unhelpful. Not so, for in that case the light is produced by the action of individual atomic particles and you cannot radiate at 1 MHz (from Wayne's example) with a single atom. Had an MRI scan recently? What's an MRI of a vacuum look like? -- ================== Remove the "x" from my email address Jerry, AI0K ================== |
