But the only truly indisputable thing was that the experiment did not reveal the movement of the Earth relative to the ether. 5 If the substance is non-dispersive then the phase velocity and the modulus of the ray velocity are equal in the frame fixed to the local ether. 6 Fresnel considered the ether as an elastic medium. Therefore the squared speed of propagation of the light waves was inversely proportional to the ether density. In order that the speed of light in a transparent substance were c/n < c, the ether density inside the substance had to exceed the universal ether density by a factor n2 .

8. Fizeau’s device to determine the time of the round-trip of light. The toothed wheel divides the light beam in pulses passing between the teeth. After the pulses are reflected on the mirror, they can be recovered through the following space between teeth, provided that the wheel revolves fast enough. In Search of the Ether during the round-trip of the light. 5 km from the wheel, the light then traveled 17 km in 1/18,000 s, which means a speed of 306,000 km/s. In 1850, Foucault improved Fizeau’s device by substituting the wheel with a rotating mirror; in this way he measured the speed of light in air and water, confirming that the light propagates slower in water than air, as predicted by the wave model.

If the Earth moves with velocity c, then the angle of aberration is such that tg = V c In the general case, let be the angle between the velocity V and the ray direction in the frame where light travels with speed c, and the corresponding angle in the frame moving with velocity V relative to the former one. 4 Clearly, if the Earth always moved with the same velocity V then the phenomenon would not be detectable because the entire sky would be displaced in a permanent way, hence it would be impossible to notice such displacement.
