Classical ether theory explains the Fizeau experiment

Emil Falkner

Abstract:Regardless of the fact that A. Michelson and E. Morley explained the Fizeau Experiment [1, 2] in a very simple classical way [3], this exaperiment is sometimes used to demonstrate the validity of special theory of relativity[4]. Because some other experiments [5, 6] show that Doppler effect, which is generated within moving Medium, influence the average speed of light, it could be rather interpreted as an argument against special theory of relativity.

An attempt to measure the speed of light in the flowing water was accomplished 1851 by H. Fizeau [1, 2], whereby it turned out that the addition of the speeds does not correspond to the usual composition of vector values. It was shown however that the measurements confirm the ether drag theory, whereby the ether is to be only partly carried. Since the speed of light is in a medium also frequency dependent, Fresnel’s theory cannot completely be in this case free of errors. Later it was shown that the results of Fizeau experiment can be derived by use of the relativistic addition of the speeds, if it is limited to small speed of the medium (M. Laue) [4], with the problem that relativistic addition of speeds is neither mathematically nor physically an addition but only a rule for the computation of a transcendental function of the sum of two numerical values. Thus only possible physical explanation remains still the theory of the gravitationally carrying ether [7, 8, 9], which also interprets the zero-result of the Michelson Morley experiment. This theory appears completely plausibly, due to the fact that a mass can be assigned to the ether as soon as an electromagnetic field is applied. It is obvious that everywhere in the space an electromagnetic field must be present because electromagnetic radiation of most different wavelengths constantly thwarts each point of the universe. Under others also A. Einstein deduced a relationship between mass and the electromagnetic energy [10].

Because the flowing quantity of water possesses, compared with earth an infinitesimally small mass and thus gravitative carrying of the ether by water is not possible, it must be proceeded from the conception that in the water two different speeds are to be considered: The speed of light c in the empty gaps, in which electrons has no influence on light and an (average) speed of light, which is completely bound to the matter (electron clouds). Obviously only the speed of light in the matter portion can be affected by movement, while the speed in the not-material massless gaps remains unchanged. Thus the time, which is necessary for light to pass a distance of the length L in the water, can be simply computed. For the water at rest we can write:

L1 is the material (ponderable) distance portion, i.e. the sum of all molecular ranges of the regarded optical path, which interact with the ray of light, Abbildung in dieser Leseprobe nicht enthaltenis the uninfluenced ether portion of the optical path and it is: Abbildung in dieser Leseprobe nicht enthalten. By division of both sides of the above equation byLone receives:

After transforming the equation an expression for the refractive index of the medium results:

The average speed of light in a medium is obviously a simple combination of two speeds, which are calculated in a conventional way.
