Yes it is, Henry is correct on that point.

The above number is from source to detector at

Yes, but that doesn't tell you the end result because
the waves move past that point while the light is in
flight.

Yes it does, you need that to work out the phase
of the wave passing your point.

Not really, he confirmed Jerry _did_ include the
ring speed so he proved you wrong. Still, you

Nope, she programmed the speeds correctly and
that is the result, look at the code and see
for yourself.

The reference point where the emission is in-phase
is the current location of the source.

I was right, you are wrong again.

Not from source to detector, and the source is where
the waves start out in phase.

Follow the red wave back from the detector anti-clockwise
to the yellow dot and you get about 7.8 waves. Follow the
blue wave clockwise (the last bit has been overlayed by
the red) and you get about 11.2 waves. However, notice
that the waves at this time are NOT in phase at the yellow
dot because they move at differentn speeds past it. The
waves ARE in phase at the detector because they are both
9.5 waves away from the source which is where they start
out in phase.

Still you cannot even look at a simple picture and see
what is obvious, the waves hit the detector in phase
which means NO fringe displacement.

NO IT ISN'T, WILSON IS WRONG.

Another believer in tick fairies.
http://www.androcles01.pwp.blueyonder.co.uk/Dualwave.gif
24 ticks blue, 24 ticks red, same frequency,
different distance, different speed, different Dopper shift.
That's two that idiots that can't count. I wonder how many more
there are...

He is correct, I already sketched it in another reply so
see the copy below. In time 1/f, the first wave moves a
distance (c+v)/f while the source moves a distance v/f.
The second is therefore emitted c/f behind the first and
they then move with the same speed so the distance between
the waves remains that value as it propagates. That is the
wavelength.

You cited the wrong diagram, this one is correct:

http://www.androcles01.pwp.blueyonder.co.uk/Sagnac/MechSagnac.gif

The teeth on the wheels are equally spaced.

No, you're own your own this time, even Henry got it right.

The number 9.5 is from the source to the detector so
it is (2*pi*R)/9.5 for both waves.

http://www.georgedishman.f2s.com/Henri/SameWavelength.png

Or you can count from the yellow dot to the
green dot:

http://www.georgedishman.f2s.com/Henri/NumberOfWaves.png

lambda_blue =(2pi + alpha)R / 11.2
lambda_red = (2pi - alpha)R / 7.8

You get the same wavelength by either method.

The number from the emision point is 13 blue, 6 red.
