You could perform the same experiment and apply the same equation to water flowing around a circular pipe. The aspect of the standard Sagnac explanation that IS related to SR is the fact that it shows the rays moving at c+/-v wrt the source....impossible according to SR.... >Paul www.users.bigpond.com/hewn/index.htm The difference between a preacher and a used car salesman is that the latter at least has a product to sell.

My animation is based on light reflecting from a moving mirror at the incident angle and speed. That is where it falls down. Light does not reflect in that way, as I have shown elsewhere. My animation still shows a reduced fringe shift and sideways displacement of the rays. > >Paul www.users.bigpond.com/hewn/index.htm The difference between a preacher and a used car salesman is that the latter at least has a product to sell.

Don't be too hasty George.

The Sagnac experiment: - Given an inertial frame which is the reference for all speeds mentioned below.

That is, all speeds are relative to this non-rotating frame. ============================================================ > >> TIME = DISTANCE TRAVELED / LIGHT SPEED >> time = (D+d)/c >> tf = (2*pi*r + tf*v)/c >> >> How the hell can this "prove SR wrong"? :-) You cannot repeat your claim which you now have realized was wrong, admitting that is no option, so what can you say? Behold: > What you have done is not related to SR in any way. You could perform the same > experiment and apply the same equation to water flowing around a circular pipe. Refutation by water pipes? Plagiarizing Sue? :-) THIS IS WHAT RELATES THE CALCULATION TO SR: ------------------------------------------- #=> The speed of the light emitted in the forward direction is c. #=> The speed of the light emitted in the backwards direction is c. Let D be the circumference of the circle, and let d be the distance the source moves between the light is emitted and is back at the source. So we have: TIME = DISTANCE TRAVELLED / LIGHT SPEED (your own words, Henri) tf = (D+d)/c tf = (2*pi*r + tf*v)/c tf = 2*pi*r/(c-v) tb = (D-d)/c tb = (2*pi*r - tb*v)/c tb = 2*pi*r/(c+v) delta_t = tf - tb = 4*pi*r*v/(c^2 - v^2) Setting w = v/r, A = pi*r^2, g = (1 - v^2/c^2)^-0.5 we get: delta_t = (4Aw/c^2)* g^2 The g^2 will obviously be unmeasurable different from 1 for any practical Sagnac experiment. So SR predicts delta_t = 4Aw/c^2 which is in accordance with enumerable practical experiments. Prediction correct, SR confirmed. ================================= AND THIS IS WHAT RELATES THE FOLLOWING CALCULATION TO THE EMISSION THEORY: -------------------------------------------- #=> The speed of the light emitted in the forward direction is c+v. #=> The speed of the light emitted in the backwards direction is c-v. Let D be the circumference of the circle, and let d be the distance the source moves between the light is emitted and is back at the source. So we have: TIME = DISTANCE TRAVELLED / LIGHT SPEED tf = (D+d)/(c+v) tf = (2*pi*r + tf*v)/(c+v) tf = 2*pi*r/c tb = (D-d)/(c-v) tb = (2*pi*r - tb*v)/(c-v) tb = 2*pi*r/c delta_t = tf - tb = 0 So emission theory predicts delta_t = 0, while enumerable practical experiments shows delta_t = 4Aw/c^2 Prediction wrong - emission theory falsified. ============================================= > The aspect of the standard Sagnac explanation that IS related to SR is the fact > that it shows the rays moving at c+/-v wrt the source....impossible according > to SR.... The above IS the standard calculation of SR's prediction for the Sagnac experiment. It is based on the 2. postulate of SR which says that the speed of light is c in the inertial, non-rotating frame, and it says nothing about what the speed of light is in any other frame. But tell me this, Henri. What kind of transformation do you use when you transform the speed of light from inertial non-rotating frame to the non-inertial rotating frame? Can you show me the transform equations? Paul |
