I didn't say it was. And it isn't we can say that Doppler shift doesn't
change the light wave itself, it is an effect on what a particular observer
measures about the wave.

Your main problem is that you have preconceptions about the wave nature of
light and its 'frequency'. In reality you have no model and are just raving.

Wavelength is absolute and invariant. The path lengths are different therefore
the rays are out of phase when they meet. End of story.

The detection point for any particular element is at rest in the nonrotating
frame. SR relies on that too,... so are you now agreeing that Einstein was an

They are vital for hte determination of the distance vt, a distance that is
used identically in b oth SR and BaTh.

I think it's time you read a little more about this.

Because it is the model that works.

You are emulating inertial in trying to explain the behavior of light by using
classical wave thepory....when it has been shown conclusively that light is not
like that.

Let's forget about oscillations and frequencies. They are totally undefined and
you two certainly haven't a clue as to what they might imply.
Let's just accept the BaTh 'wavelength' explanation. It works. The path lengths
are different therefore each path contains a different number of wavelengths
and the rays are out of phase when they reunite. End of story.

that's the other demo. THe stationary wave is put there purely so you can see
the phase difference.

At constant rotation speed, the fringes do not move. During any speed change,
they move to a new displacement.

I think so ...but that should be reversed at the detector, where there is a
similar reflection.
It would be even more interesting if the wave phasing reversed direction at the
reflection. For example, have you ever played squash? If you put topspin on a
ball, it comes back to you with backspin on it, after bouncing off the front
wall. I have often wondered if this is another complication in sagnac.
