EB; "I do not understand why and how Snell's law is recovered. What is an incident medium? Isn't rather a wave possibly incident? Which KRrefraction experiments and which KRrefraction effect do you refer to? Do you really maintain that refraction matters in the Michelson Morley experiment?"
1. M&M. Yes. I've found that probably nothing matters more in unravelling the paradoxes than the process at refractive and reflective planes, and it's effects. I have a paper just accepted for publication discussing this and explaining the Kantor and B&B interferometer anomalies. The Maxwell near/far field 'Transition Zone' (TZ) fine structure at the surface of all matter controls the process. I's equivalent to Earth's EM 'shock' (see Kingsley essay Fig of 'Cluster' findings), and Feist's detector discussed above, where light changes speed by relative v to the new local medium c/n. Which is why it's found to be c in all media.
2. Kinetic Revere Refraction (KRR). ALL experiments find the same. (Ko, Chuang 1977, Mackay, Lakhtakia 2006). When observed from an incident frame, light at near normal incidence passing into a co-moving medium appears to be 'dragged' by the medium (Grzegorczyk 2006). Snel's Law is then famously violated by the relative media motion. But when the light 'path' in the medium is observed from at rest in the MEDIUM frame, it's found that the REAL path is REVERSED.
It is this acceleration by the observer into the new frame (and thus at rest in the propagating medium) that recovers Snel's Law from his new frame.
3. Now put the two together. In the bizarre 'non linear optics' effects Snel's Law is similarly violated at the TZ, Fresnel refraction becomes what is termed 'Fraunhofer refraction', and frequncy changes. The TZ position is wavelength dependent for aerial emitters, but within 1 micron of the surface of refractive and reflective planes.
The solution explains why moving mirrors reflect light at c wrt the incident medium NOT wrt the mirror. In fact the initial reflection off the protons is at c wrt the mirror, but the electrons form a magnetohydrodynamic shock (as Kinsgsly graph) with the 'air' side of the turbulent TZ at rest in the air frame, so re-emitting at c with respect to themselves, as may be expected. All then falls into place.
The 'incident medium is the 'approach' medium, which may be a near vacuum, but none the less the 'outer layer' TZ electrons are propagated in that frame (explaining photoionization) and re-emit in that frame.
When I test that model on the dozens of astronomical anomalies in existence, they all fall into place like a giant jigsaw puzzle; re-ionization, aberration, ellipticity, IFR, Pioneers/Flyby anomalies, galaxy recycling, lensing, kSZ effect, intrinsic rotation, singularities, quasar jets, frames last scattered, CMB anisotropic flow, curved space-time, the LT, twins paradox, the list is almost endless. My essay gives the simple kinetic logic. It may at first seem complex, but the only issue is unfamiliarity.
Do ask about or query any part.
