  1. Thanks for these posts which I have found inspiring. On the microwave power front I calculate that for a cavity magnetron transmitting at a wavelength of 1 x 10**-3 m to achieve a photon rate as low as 1000 photons per second a power of 2 x 10**-24 watts would be required. It would be difficult to envisage a system where this would not be swamped by noise. I chose 1000 photons per second as rate that one might expect to be detectable. This supports AJB's post.
  2. I believe all electromagnetic radiation is comprised of photons. Is there any experimental evidence that radio transmitters emit photons rather than continuous em waves?
  3. Hi. I'm trevorb. I completed a physics degree in 1975 and since then worked in computers but never lost my fascination for physics.
