WebMar 27, 2024 · The photon has spin 1; a vacuum fluctuation of the electromagnetic field must have spin 0. Footnote 2 It is important to point out that, other than the preceding comment, this article does not discuss fluctuations of the QED vacuum, on which there already exists considerable literature [ 11 , 12 , 13 ] and references therein. Web31. Oddly, polarizing sunglasses provide a quite solid proof that photons are spin 1. That's because if you rotate polarizers by only 90 ∘, you will find that you can break photons down into two mutually exclusive populations of photons. That is geometrically possible only if …
