What would happen if we had super fast and super sensitive oscilloscope that could probe and record into memory electric or magnetic field oscillation created by single photon that would fly near the probe/antenna?
Can antenna detect change in electric or magnetic field of single photon without being directly hit by the photon? The photon just flies nearby but doesnt hit the solid conductor of the antenna.
If 1. is indeed possible, what would the recorded waveform look like? How long will it be?
I know its going to be sinusoid, and I think the lenght should be 1 wavelenght but the thing is, having just one sinewave oscillation with instant start and stop is like doing FFT with rectangular window function, its going to create harmonics and distortion becose of the rapid start/stop.
That got me thinking that if the electromagnetic field oscillation of single photon was just one wavelenght long, it would mean there must be higher wavelenght photons riding alongside it to represent the upper harmonics caused by the rectangular window single cycle duration, its probably completly wrong but I thought about it.
Then I thought maybe the single photon waveform is more like gaussian window, longer than one wavelenght, with smooth increase as the photon gets closer and closer and equaly smooth "fade out" as it gets away.
