They recognized okay we cant measure the speed of light with enough precision to detect has it gotten slowed down by the ether wind or sped up by the ether wind but what we could do and this is what Michelson and Morley did do and Im gonna do an oversimplification of the experiment is that okay you have a. A beam of light actually continuous not pulsed as in the animation below is split when it strikes a transparent plate.

The Michelson-Morley Experiment This animation shows the path of light traveling back and forth between the mirrors assuming the apparatus is at rest relative to the aether.
Michelson morley experiment animation. Michelson and Morleys experiment was devised to observe the influence of a hypothetical ether that supposedly filled all space on the speed of light depending on the direction of the Earths motion. Part is transmitted part reflected. Albert Michelson and Edward Morley tried to measure the speed of light in different directions using light interferometers.
With this in mind please view the animation below which starts with a demonstration of aberration of light and then extends this to the transverse arm of the Michelson Morley experiment where the aberration theory applies. Michelson designed and built an interferometer using a similar principle. This simulation allows the user to experiment with the interferometer by changing the speed of light and rotating its plane.
Read the original 1887 paper by Michelson and Morley. When the two divided beams return to the plate partial reflection and partial transmission also combines them. Michelson and Edward W.
The left part of the detector and the number of photons is reduced per length unit animation. As in Exercise 221 we have t1 2L1 c 1 p 1 v2c2 t2 2L2 c 1 p. A video I made for a school presentation back in 2007.
Then show t 2 c L 1 v2 2c2. This web page contains a simulation that recreates the Michelson-Morley experiment. After the failure of the famous Michelson-Morley experiment of 1887 1 given its inability in providing the own speed through space the discovery.
This movie simulates the set-up used in the Michelson-Morley experiment including the non-existent aether wind they were trying to detect. The main objective of this experiment was to prove the existence of the medium in which light propagated. The film also explores the personal side of Michelsons life notably his talents as a painter and a violinist.

Michelsons experiments and theories including the famous Michelson-Morley experiment are clearly explained in the film through narrative and animation. Play with a Flash animation that shows a simplified view of the experiment. The signals are then reflected back and recombine at a.

Detecting the Aether Wind. Part is transmitted part reflected. J Phys Math 11.
An interferometer is an apparatus that splits light at right angles using a half mirror and then measures the interference of the beam of light with itself. When the two divided beams return to the block partial reflection and partial transmission also combines them. Originally Michelson designed his.
As you can see the aim of the experiment was to split a beam of light into two. Suppose in the Michelson-Morley apparatus that L L1 L2 6 0 and that there is a contraction by a factor of p 1 v2c2 in the direction of the ether wind. Morley set out to find the ether indirectly by measuring very precisely the properties of light waves passing through it.
The main objective of this experiment was to prove the existence of the medium in which light propagated. The fully reflecting mirrors were positioned at equal distances from the half-silvered mirror so that the two beams of light would have to travel the same distance to. Schematic of the Michelson-Morley experiment.
In the eighteen-eighties Albert A. Schematic and animation of the Michelson-Morley experiment. Naturally something that allows solid bodies to pass through it.
Detecting the aether wind was the next challenge Michelson set himself after his triumph in measuring the speed of light so accurately. We have to mention here that the most spectacular realization so far of Michelsons interference techniques is the successful detection first in 2016 of gravitational waves by a scaled-up version of the interferometer. The basic idea is to detect the time difference between light going upstream then downstream and light going across shore and back.
22 The Michelson-Morley Experiment 5 Example Exercise 224. The definitive experiment was carried out by Alvager et al Physics Letters 12 260 1964. A beam of light is shot toward a beam splitter that sends the two resultant beams to different mirrors.
