What was the negative result of Michelson-Morley experiment?

The experiment was performed between April and July 1887 by American physicists Albert A. Michelson and Edward W. The result was negative, in that Michelson and Morley found no significant difference between the speed of light in the direction of movement through the presumed aether, and the speed at right angles.

What was the conclusion of Michelson-Morley experiment?

The Michelson–Morley experiment is the most famous null experiment in the history of physics. They found that the velocity of the Earth relative to a hypothesized ether was effectively zero. This result refuted virtually all of the then current ether theories.

What are the findings of Michelson-Morley experiment?

The experiment performed compared the speed of light to notice the relative motion of Earth through ether. However, the conclusion of the Michelson Morley experiment comes out to be negative. It means that they found no difference between the speed of light while travelling through ether.

What was the purpose of the Michelson-Morley experiment what were its results?

Michelson-Morley experiment, an attempt to detect the velocity of Earth with respect to the hypothetical luminiferous ether, a medium in space proposed to carry light waves. First performed in Germany in 1880–81 by the physicist A.A. Michelson, the test was later refined in 1887 by Michelson and Edward W.

Why was the apparatus of Michelson-Morley experiment rotated through 90?

The combination generates interference fringes of dark and bright bands. Michelson and Morley rotated their interferometer by 90°, interchanging the role of the two light paths. They observed the combination of the two beams in the original orientation and their combination after rotation by 90°.

When did Michelson discover the speed of light?

His Annapolis experiment was refined, and in 1879, he measured the speed of light in air to be 299,864 ± 51 kilometres per second, and estimated the speed of light in vacuum as 299,940 km/s, or 186,380 mi/s.

How does a Michelson interferometer work?

The Michelson interferometer produces interference fringes by splitting a beam of light so that one beam strikes a fixed mirror and the other a movable mirror. When the reflected beams are brought back together, an interference pattern results.

Who have disproved an ether hypothesis experimentally?

Therefore the Michelson-Morley disproves the existance of aether understood as the material medium where the light has a relative velocity zero, or what is the same the medium needed for propagating the electromagnetic waves.

Who disproved the luminiferous ether?

In 1905 Einstein rejecting the ether theory Einstein’, by Lincoln Barnett, London, 1949, page 38. Einstein’s special theory of relativity states that the light velocity is the highest speed in this universe or nothing can travel faster than the speed of light.
