It always remains the same (at any constant speed) : : So Jerry's simulation is not useless, you finally : learned what it shows. What is doesn't show makes it only semi-useful. It doesn't show the Doppler shift Grandpa sees, yet the point of view is that of Grandpa's. : You can also now watch the : phase of the two signals as they pass the yellow : dot. Can you see that their phase changes with : time? Yes, I saw that straight away with Rev 0, (now Rev 4.1) and Jeery doesn't show it. That's where the frustration comes in and people get angry because the OP is blind to the obvious. One has to learn to observe and not leap to conclusions. Jeery's comments on that page are ridiculously prejudiced and WRONG.

Even George undestands that the emission point doesn't move even thpough the source does. Where George is hopelessly wrong is in assuming the rays always meet in phase. Henri Wilson.

That's what I said. The is a phase difference at the detector.....determined by the difference in number of wavelengths in each path. >Jerry's code is correct.

George, the rays are not in phase when they reunite. You seem to think this should be the case just because the travel times are the same. That does not follow.
