This only works if you forget that light is quantized. The place the weirdness really comes in is that if you shoot single photons at a time, you observe the same effects.

- yarg 4y agoIt's not that weird. You can consider a wave passing through a filter as a sum of two orthogonal waves, rSin(θ) + rCos(θ), θ being the angle between the light-wave and the filtered angle, r being the amplitude of the wave. One wave gets eliminated, and whatever exits exits at the only angle it can, the angle orthogonal to the filtered angle.
- yarg 4y agoI wasn't particularly clear here; but I'm not actually wrong. The reason, for example, that the 45 degree filter leaves 1/(2^.5) ~= .7 It's just the trigonometric break down of the right-angle isosceles.
- aidenn0 4y agoIt's only weird if you think of light as just being particles. Once you realize it's a wave too, then the math all works out just fine.
