Consider you are on the ring and rotating with it at v.
Next to you is another ring that is NOT rotating.

At certain instant, you emit two pulses of light in opposite directions around
the ring. You also place a mark on the nonrotating ring.

What happens to the mark?
Answer: it appears to move away from you at v.
By the time the pulses return, the mark has moved a distance vt away.

Of course YOU have no way of knowing that the mark represents the original
position of the emission point or that you are rotating with a peripheral speed
of v. You have every reason to believe that both pulses move away from you at c
and travel the same distance, 2piR in the same time. You are therefore
mystified by the fact that they are not in phase when they reunite.

This is a perfect example of how the use of rotating frames can be misleading.
In fact, the rays travel different distances EVEN IN THE ROTATING FRAME.
AND their wavelengths are the same.

Your model of a photon is a drawing of a frozen sine wave moving at c wrt
little planet Earth.
How pathetic.....
