redkiss Posted March 12, 2016 Author Posted March 12, 2016 Can I use Doppler or I have to look ZERO ? I have one source and one sensor but what about for example 4 sensors ?
Strange Posted March 12, 2016 Posted March 12, 2016 I think you need to explain a bit more. Can you use Doppler for what?
redkiss Posted March 12, 2016 Author Posted March 12, 2016 (edited) sorry I want to measure table's position respect to what ? exist Doppler ? exist ZERO ??? help me please I studing about GPS technology I have big problem I see RED or there is ZERO and respect to what table is moving ? MORE LONG ARM ??? = MORE RED ??? or MORE ZERO ?? sorry ??? Edited March 12, 2016 by redkiss

Klaynos Posted March 12, 2016 Posted March 12, 2016 I wont to prepare test ( what will be if Arm will be more longer /shorter ) What kind of test? Which arm?
John Cuthber Posted March 12, 2016 Posted March 12, 2016 I wont to prepare test ( what will be if Arm will be more longer /shorter ) You seem to think that we already understand what you are asking. We do not. Please start from the beginning. Tell us what you want to know.
Mordred Posted March 12, 2016 Posted March 12, 2016 (edited) Well I'm guessing this is a homework question on what will be the redshift of the arm compared to the craft. Or to each sensor position. Edited March 12, 2016 by Mordred
redkiss Posted March 12, 2016 Author Posted March 12, 2016 (edited) The Michelson–Morley experiment was performed over the spring and summer of 1887 by Albert A. Michelson and Edward W. Morley at what is now Case Western Reserve University in Cleveland, Ohio, and published in November of the same year.[1] It compared the speed of light in perpendicular directions, in an attempt to detect the relative motion of matter through the stationary luminiferous aether ("aether wind"). The result was negative, in that the expected difference between the speed of light in the direction of movement through the presumed aether, and the speed at right angles, was found not to exist; this result is generally considered to be the first strong evidence against the then-prevalent aether theory, and initiated a line of research that eventually led to special relativity, which rules out a stationary aether.[A 1] The experiment has been referred to as "the moving-off point for the theoretical aspects of the Second Scientific Revolution".[A 2] Michelson–Morley type experiments have been repeated many times with steadily increasing sensitivity. These include experiments from 1902 to 1905, and a series of experiments in the 1920s. More recent optical resonator experiments confirmed the absence of any aether wind at the 10−17 level.[2][3] Together with the Ives–Stilwell and Kennedy–Thorndike experiments, Michelson–Morley type experiments form one of the fundamental tests of special relativity theory.[A 3] OK please help me evaluate how long ARM I must build to measure RED shift ! I speak here only about 360/24h speed later we can add more arms ( more mirrors ) source--------sensor Sorry mirror = sensor Source = EM wave ( radio, light ,.. ) How long arm is good to test RED ?

swansont Posted March 12, 2016 Posted March 12, 2016 I understand that English isn't your first language, but there is a lot you aren't including in your question. You mention GPS, but don't explain how that fits in. You want to measure the red shift, but the red shift of what signal?
redkiss Posted March 12, 2016 Author Posted March 12, 2016 (edited) Sorry ! mirror = detector ( sensor ) source ------------------sensor I'm sorry it is GPS ? sorry Radio---------------------------Signal detector ( after detection we have emission ) sorry sorry stupid question ??? ??? Laser --------distance--------mirror = radio signal ---------distance-----------detector INTERFEROMETER's ARM = RADIO's ARM ? Radio Signal = Light = EM wave ? I'm sorry I hope You are able read my post in english I want to measure in home 360/24h speed I'm trying to find distance to measure RED ? I have huge problem ? it is possible ? or we have ZERO ? Hey ??? Edited March 12, 2016 by redkiss
EdEarl Posted March 12, 2016 Posted March 12, 2016 GPS, Ligo and the aether experiments have totally different purposes. We would like to help, but do not understand. Perhaps Google translate would help.

EdEarl Posted March 12, 2016 Posted March 12, 2016 i want to measure in home 360/24h speed Am I able read Earth's motion ? Do you want to measure the speed of Earth's rotation, speed of revolution around the sun, or combined motion of Earth, the Sun orbiting around the Milky Way Galaxy, or something else? do we have Doppler ?Who is "we." The Doppler effect occurs naturally from light coming from stars, and can be used to measure their speed because we can measure the receiving wavelength and can know the transmitted wave length from spectrographic studies. You might use the Doppler effect to measure the rotation speed of the Earth, if that is your purpose. However, the change in wavelength of light due to the rotation of the Earth would be quite small, about 0.0001%. I don't know what it would take to measure that amount of wavelength difference. radio wave = light wave ? = EM signal ?Yes, light and radio waves are EM radiation, also x-rays, infrared, and ultraviolet. what is better ONE arm or 4 arms ? ( precission ?) http://images.tinypic.pl/i/00765/8g7j8biccn4d.jpg I think this device will not do what you want. The got zero because they were trying to measure something (aether) that does not exist. The speed of light is always the same no matter where it comes from, and no matter the direction or speed of the source. The equipment sown in the picture has the light source on the device, which means it will never measure a Doppler effect. You would need a light source not on the Earth to measure a Doppler effect caused by motion of the Earth. Since the Earth is spinning on its axis and orbiting the Sun, and the Sun is orbiting the Galaxy, it would be difficult to measure each of these independently. sorry sorryThere is no need to apologize; you have done nothing wrong. DO WE HAVE ZERO in Michelson Morley ? ( I wan to build my own tool I can not understand how they proved ZERO ? ) In one ARM i can see DOPPLER 4 arms I can not understand how it works How 4 arms showing ZERO ? I think the Michelson Morley equipment will not do what you want. I hope I have answered the right questions. If not, ask again.

Strange Posted March 13, 2016 Posted March 13, 2016 Firstly, experiments like MIchelson-Morley and LIGO use two arms because they use interferometry in order to measure very small differences (fractions of the wavelength of light). You are not going to be able to make very accurate measurements with one arm. Look here: https://en.wikipedia.org/wiki/Interferometry Maybe it has a page in your language. Secondly, there will be no Doppler effect. That happens when there is a difference in speed between the source and the receiver. That is not the case with an arm with a transmitter at one end, and a sensor at the other. For example, you hear the Doppler effect when a car drives past you, but not when you are driving at the same speed as the other cars. You mention GPS in the title (I don't know why). That is one case where the Doppler effect is important. The receivers have to scan a wide range of frequencies, either side of the transmitted signal, because the satellite could be moving towards or away from the receiver.

WRT the observer. And don't tell us to do our homework The idea doesn't make sense. If you are asking us for help then it's because you know more than you do. So you know that we have already done our homework. You are the one who needs to learn.
