But what happen at the MOVING detector has EVERYTHING to do with the Sagnac effect. That is the flaw in your analysis, you do the analysis for some fixed point in the inertial frame, and NOT what is detected in the moving detector. You are not analyzing the Sagnac effect but some other 'Wagnac' effect which has different predicted and observed results. You correctly analyze the wrong effect and then claim it is Sagnac. > You are clueless. Sorry .. its you who have no clue. Despite years of the clues being spoon-fed to you.

One, the strobe, you cannot change. The other you can, by changing the RPM. The disc is ~12" in diameter, so the circumference must be 12 pi = 37.7" 33 RPM is 37.7 * 33.3 = 1255 inches/minute, or ~21 inches/sec. The strobe is 60 Hz, so the pips have to be 21/60 ~= 1/3" apart, there are 60 of them and it will appear to stand still at 33 RPM. Definitely nothing to do with Einstein's relativity, right? The other way to make it stand still is let it stand still. Now comes a cute trick. We take off the pips and replace them with windows in a pipe (a light guide is fine), and put a strobing light in the pipe. Then with mirrors we reflect both lights onto a white card, and at 33 rpm the illuminated spots on the card stand still at 33 RPM (and 0 RPM). So you have two spots of light, you can superimpose them or not, and as long as they remain the same distance apart the turntable has a speed of 33.3 RPM. The gap between the spots is the phase angle. If you stop the turntable, you can move it back a forth 1/3" and change the phase angle by bringing the spot from the previous window or the next window into line with the spot from the fixed light. Next we take those two spots of light, superimpose them on a diffraction grating, and get a fringe shift. Now a microscopic movement of the turntable produces a noticeable phase shift. What Sagnac does is replace the fixed light outside the turntable with a second light in the pipe, directed to travel in the opposite direction. Still nothing to do with Einstein's relativity, right? I won't give you any more yet, I know you have a short attention and will only snip and ignore it.

And that's what Androcles was hinting at too! Very good! I'm laughing, that's delightful. But now I am having trouble with it. The wavelength should stay the same, yes. But the frequency stays the same too. The wavelength is the same because you don't measure wavelength back toward the source when it emitted the wave, you measure it in the direction of the wavefront. So in a time interval t units long, one side emits n cycles at speed c+v and the other side emits n cycles at speed c-v. Both arrive at the sensors at the same time. During the time for one wave to pass from the c+v side, one wave will pass from the c-v side too, slower. I don't see that this gives us a phase shift or a frequency difference or anything for an interferometer to pick up. It looks to me like the version that has the light emitted at some speed, call it c+v, and it stays that speed despite any reflections or refractions, is probably not compatible with Sagnac. But there are lots of other versions to try out, and I doubt any of your results depend on reflections. > >> > and at the same time shown why Sagnac refutes SR. > >> > >> Which, of course, is also incorrect, as Sagnac does not in any way > >refute SR> and never has.

Just as they misinterpreted yours, I think you're misinterpreting them. They can have the rays move at c but one of them has to travel farther because of the movement of the mirrors etc. ============================================= The flight attendant moves at 3 mph max, yet travels 3000 miles in 6 hours. Velocities are frame dependent. According to SR, light moves at c in ALL frames of reference. Some idiots even say that's the second postulate, although its really a conclusion in � 5. The Composition of Velocities. Ref: http://www.fourmilab.ch/etexts/einstein/specrel/www/ Such a conclusion is called "reductio-ad-absurdum" in mathematics. Sagnac refutes SR because it requires that the rays move at c+v and c-v wrt the nonrotating frame and c with respect to the rotating frame. Don't stand next to a rotating Sagnac or your wristwatch will slow down, you are in the c+v frame. |
