Experimentul Michelson–Morley, unul din cele mai importante și celebre experimente din istoria fizicii, a fost efectuat în 1887 de Albert Michelson și Edward Morley la ceea ce este astăzi Case Western Reserve University. Este în general considerată ca fiind prima dovadă solidă împotriva teoriei eterului.
Michelson calculated that an aether windspeed of only one or two miles a second would have observable effects in this experiment, so if the aether windspeed was comparable to the earth’s speed in orbit around the sun, it would be easy to see. In fact, nothing was observed. The light intensity did not vary at all.
The Michelson-Morley Experiment In 1887, Albert A. Michelson and Edward W. Morley tried to measure the speed of the ether . The concept of the ether was made in analogy with other types of media in which different types of waves are able to propagate; sound waves can, for example, propagate in air or other materials.
Datos de Michelson-Morley. El experimento de Michelson-Morley se ha repetido durante un periodo de unos 50 años, con crecientes niveles de sofisticación. El resultado general da un alto nivel de confianza en que el cambio de longitud de onda es consistente con cero. L (cm)
Der Michelson-Interferometer wurde das erste Mal zwischen April und Juli 1887 im berühmten Michelson-Morley-Experiment angewandt. Die beiden Wissenschaftler Albert A. Michelson und Edward W. Morley waren die Experimentatoren und Namensgeber des Experiments.
The most famous and successful was the one now known as the Michelson-Morley experiment, performed by Albert Michelson (1852-1931) and Edward Morley (1838-1923) in 1887. Michelson and Morley built a Michelson interferometer, which essentially consists of a light source, a half-silvered glass plate, two mirrors, and a telescope. The mirrors are ...
The. Michelson-Morley experiment. The German-born American physicist A.A. Michelson set the early standard for measurements of the speed of light in the late 1870s, determining a speed within 0.02 percent of the modern value. Michelson’s most noteworthy measurements of the speed of light, however, were yet to come.
