Dr. Henri Wilson skrev:
The wavelength of any TRAVELING wave is absolute and frame independent.

The 'wavelength' of an OSCILLATOR (such as a spinning wheel), if defined as
'the distance it travels in one of its cycles', IS of course frame dependent.

Oscillators don't actually possess 'wavelengths'.
I think that's where your confusion lies.

Quite.
Oscillators don't have wavelengths, and this wavelength is defined as
'the distance it travels in one of its cycles'.

And these oscillators without a wavelength which IS of course frame dependent,
can explain why the invariant wavelength of TRAVELLING waves can be frame
dependent after all, so that the number of wavelengths in the two rays
can be different, and BaTh can predict that Sagnac can detect rotation.

Confusion?
Where?
Isn't this crystal clear?
