Sagnac isn't complicated at all. It is however bothering to you, since it falsifies emission theory. Paul

The emission theory gives the equations c'=c-v and c'=c+v whereas special relativity gives c'=c. Which equations: c'=c-v and c'=c+v or c'=c, are relevant in the interpretation of the Sagnac experiment? Pentcho Valev

Jeckyl Jeckyl I asked your brother zombie Andersen, not you. You are not able to explain c-v and c+v appearing in the interpretation of the Sagnac experiment but brother zombie Andersen is: http://groups.google.ca/group/sci.physics.relativity/browse_frm/thread/7977df6b0a4d925a?

Which equations: c'=c-v and c'=c+v or > c'=c, are relevant in the interpretation of the Sagnac experiment? > > Pentcho Valev 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. - Given a stationary circle with radius r. - Given a light source moving at the speed v around the circle. - Assume the light is moving around the circle (infinite number of mirrors). - Let tf be the time the light emittet in the forward direction uses to catch up with the source. - Let tb be the time the light emittet in the backward direction uses to meet the source. Prediction according to SR: --------------------------- The speed of the light emitted in the forward direction is c. The speed of the light emitted in the backward direction is c. So we have: 2*pi*r + tf*v = tf*c tf = 2*pi*r/(c-v) 2*pi*r - tb*v = tb*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 unmeasureable 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. Prediction according 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. So we have: 2*pi*r + tf*v = tf*(c+v) tf = 2*pi*r/c 2*pi*r - tb*v = tb*(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.
