Where photons will stop being themselves !

  1. Oct 25, 2006 #1
    I am new on this forum and would you please excuse me if this is off topic, I do not dare opening another thread for my silly question:
    I'm puzzeled by the electromagnetic spectrum when going to lower fequencies.. Is there a point where it is not photons anymore ?
    For example red light=photons, infrared= photons, microwaves= photons right? Radio waves photons? Very Low Radio Frequencies, photons?, And what if I shake a magnet in an alternative 1Hz move.... Do I still create photons ? :rolleyes:

    Yes, but the photon energy would be so low that there will be so many photons that you wouldn't notice the quantization.

    Does anyone know the lowest energy (frequency) at which individual photons can be counted?

    I think microwave (300 MHz (3 x 10^8 Hz) to 300 GHz (3 x 10^11 Hz)) is the lower bound, but I'm not sure how far down into the band detectors can function.
