EXPERIMENT OF MICHELSON AND MORLEY

The experiment of Michelson and Morley arises at the end of the 19th century, where the diverse images of the ether that the scientists constructed were managing to justify different physical phenomena, since it is the case of the hypothesis of partial dragging which was explaining the stellar aberration and the electromagnetic ether as support of the optical and electromagnetic phenomena. The physicist Michelson I realize his first experiment in the year of 1881, which consisted of measuring the speed of the land with regard to the ether with base in the calculations of the times registered by two beams of light combine that were interfered instead of an alone path as he was considering her to be Maxwell.

In the graph of interference presented by Michelson a consideration had since the effect of the ether on the land that I present, It received critiques on the part of Lorentz and other scientists, For motives that the experiment had extreme sensibility of the instrument (for the external vibrations), Apart the theoretical mistakes raised by Potier in the year of 1881 it was overlook the influence of the movement of the land in the vertical path that caused Michelson was repeating his experiment with Morley in the year of 1887.

The experiment provided a clear proof that no ether exists and that the speed of the light is constant independently of the movement of the source "(COUGHLAN y DODD, 1991, p. 9 en [1] [2],).

According to research of the scientists who did not realize this experiment, one concludes that there is no existence of the ether. Nevertheless, this itself was what he led to that it was one of the most important experiments, since with these results they allowed to verify that the above mentioned ether might not exist and one raised that the light might travel in the emptiness without any way. This derived in the Theory of Einstein’s Special Relativity, which imposed not existence of the above mentioned ether.

EXPERIMENTO DE MICHELSON Y MORLEY

El experimento de Michelson y Morley surge a finales del siglo XIX, donde las diversas imágenes del éter que los científicos construyeron lograban justificar diferentes fenómenos físicos, como es el caso de la hipótesis de arrastre parcial la cual explicaba la aberración estelar y el éter electromagnético como soporte de los fenómenos ópticos y electromagnéticos. El físico Michelson realizo su primer experimento en el año de 1881, que consistió en medir la velocidad de la tierra respecto al éter con base en los cálculos de los tiempos registrados por dos haces de luz que se interferían en lugar de una sola trayectoria como la consideraba Maxwell.

En el diagrama de interferencia presentado por Michelson tuvo una consideración ya que el efecto del éter sobre la tierra que el presento, recibió críticas por parte de Lorentz y otros científicos, por motivos que el experimento tenia extremada sensibilidad del instrumento (por las vibraciones externas), aparte los errores teóricos planteados por Potier en el año de 1881 el cual fue pasar por alto la influencia del movimiento de la tierra en el sendero vertical ocasiono que Michelson repitiera su experimento con Morley en el año de 1887.
