Fizeau test of drag

Fresnel 1818-30,  Fizeau 1851
Fresnel  proposed that matter moving at v would drag aether along but reduced by the drag factor
(1-1/n²) .   The Speed of Light (SoL) for this case is 

Fresnel’s Law:                         SoL =  c/n  + v(1-1/n²).

Fizeau tested and confirmed the Fresnel conjecture by splitting a beam and sending the half beams through water moving in opposite directions with speeds v and –v (above). The half beams were recombined and compared in an interferometer. Fresnel’s law showed aether is dragged with water/ matter at a greatly reduced speed .

Note that if a vacuum is used , where n ==  1.0000, no dragging will occur; SoL will be c.  It is hopeless to test for c anisotropy with a vacuum, as there is no mass for the aether to interact with. Yet such vacuum exps. are cited by MS scientists as proof of SR’s second axiom….
And the non-existence of aether.

Also, note that the aether motion is measured within the dragging medium, not outside it, as in the Sagnac test, which shows no reduction in v.
Another important note – for future reference in the Sagnac test -  is the unstated reference frame for Fizeau’s  experiment …… the lab frame!

Conclusion:   SoL is composed of 2 terms, one which depends only on the refractive index n, and the other is dependent  on both n and v.
