Miles's approach is highly mechanical, and still highly theoretical. It's always good to read how others attack problems like the ones you come up against, in photon and other physics type experiments. The more one reads, the wider your base of resources, and the less likely you are to unknowingly follow the same screw-up path that someone else already has. That's a nice timesaver right there.
FYI, there are mechanisms in both acoustical design of loudspeakers and loudspeaker arrays, and radar, which use waveguide shapes called "horns" and phased arrays
that result in narrow beamwidths, concentrating energy along a relatively narrow axis. For that reason, 3-D images or tables of intensity around the source are often used to characterize the beaming angles in the far field, very useful to designers who use these things. That the product is a narrow beam has nothing to do with whether the emitter is emitting particles (as loudspeakers do) in a longitudinal wave, or E/M radiation (whether particles or transverse E/M waves).
My tentative conclusion is that anyone would be very hard pressed to design an experiment that could conclusively determine which form "light" really is (in case it is not "both"). Miles, of course, is in the collision crowd, and does not cotton to fields at all. Being titled Physics, it's all -well, physical
, to him. I see his point. (Read his paper on the double slit experiment. He proposes an interesting counter experiment at the end of that paper which I wish some lab would try.) I also like the idea of fields and action at a distance and an aether, but cannot get my head around how those physically would work at the tiniest, most fundamental level. Don't forget, there are photon emitters that emit a single
photon at a time, somehow, at a user-determined rate of fire. Are those chunks of light, or little bundles of something vibrating at a particular frequency, or what?
Can a photon vibrate or contain vibrations at more than a single frequency simultaneously? Sound waves can. A complex sound wave can be broken down into the frequencies present in its waveform by using Fourier transform analysis as well as wavelet analysis. So can a complexly colored source of light, I'd bet; waves are waves, although the differences between transverse and longitudinal waves intransmission media as different as air and a nearly hard vacuum might be profound.
There always seems to be something we don't know or aren't aware of yet, doesn't there?
