Ghost is correct...as he sometimes is...
The wavelength of any TRAVELING wave is absolute and frame independent.

Doppler effect for a wave from a source moving in a medium affects both
frequency and wavelength though.

Of course....but that's not what we're talking about...

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.

Yes

Oscillators don't actually possess 'wavelengths'.

But you just defined what its wavelengtth is .. make up your mind

Idiot, did you notice I wrote 'wavelength' and not wavelength.
....which implies that this is not a true wavelength but a commonly defined one.

I think that's where your confusion lies.

I think you are showing your own confusion

And now then .. how does light move then .. is it like a moving oscillator,
where the frequency is fixed and the wavelength varies between observers, or
like a moving wave, where the wavelength is fixed and the frequency varies
between observers.

.....this is how light moves around a ring gyro.

You might be able to deduce a few facts about light from this.
