Velocity of light through a moving medium applied to the Fizeau experiment

Light travels in a moving medium through densities that differ from the density of that medium at rest. This study derives a formula for the velocity of light through a moving medium for any direction of light propagation that, applied to the Fizeau experiment, gives a fringe shift of 0.23541. The Fresnel drag coefficient applied to the Fizeau experiment offers a fringe shift of 0.20466. The mean of 0.23016 for the fringe shift observations in the Fizeau experiment confirms both expectations.

 

La lumière se déplace dans un milieu en mouvement à travers des densités qui diffèrent de la densité de ce milieu au repos. Cette étude dérive une formule pour la vitesse de la lumière à travers un milieu en mouvement pour n'importe quelle direction de propagation de la lumière qui, appliquée à l'expérience de Fizeau, donne un décalage de frange de 0.23541. Le coefficient de traînée de Fresnel appliqué à l'expérience de Fizeau offre un décalage de frange de 0.20466. La moyenne 0.23016 des observations de déplacement des franges dans l'expérience de Fizeau confirme les deux attentes.
