Michelson Definition and 110 Threads

I've just started reading the dustiest book on relativity i could find at the local library and like most others I've seen it includes the Michelson Morley experiment. I just need a bit of clarification on the formulae they use. The equations t1=2l/(c^2 - v^2)^1/2 and t2=2lc/c^2 - v^2...

I don't know how to proceed on this question. It says: A shift of one fringe in the michelson-morley experiment would result from a difference of one wavelength or a change of one period of vibration in the round trip travel of light when the inferometer is rotated 90º What speed would...

Hi, I conducted an experiment with the Michelson Inteferometer to obeserve white light fringes but I cannot explain the presence of a central black fringes. I understand a phase shift of pi is introduced in one of the beams but where/how does this shift occur? thanks

Retired Canadian physicist, Paul Marmet, has published a number of 'heretical' papers that question some fundamental principles of modern (non-Newtonian) physics. see: http://www.Newtonphysics.on.ca/ I have glanced through his paper that tries to explain errors in the math used in the...

Hi all, I've made a Michelson Interferometer with 635 HeNe, and I get nice, contrasty fringes. I have one problem - I cannot get the bright spot in the middle to turn dark! The intensity it has is like bright and brighter, but never dark. Any ideas why? The intensity of the two beams are...

okay! now I would like to discuss the problems with the Michelson - Morley Experiment [link] I believe the experiment was flawed, both technically and conceptually due to crude (19th century) methods and ill conceived assumsions for example: why should aether form an absolute reference...

Can anyone explain the following to me; what is phase difference and coherence? what actually is diffraction and why does it happen (is it something to do with Huygens principle?) why do you observe circular fringes when using the Michelson interferometer your help is much...

So I suppose you don't want the correct solution to the michelson and morley interferometer. You'd rather keep on talking about relativity, and such, as if you really understand it. The problem has been solved and there is no need for the likes of you to waste you time on it any longer. Einstein...

I thought the idea was that light should move faster coming towards the Earth than moving away but that it was found that the two speeds were the same; but isn't the Earth moving towards something adding to its rate just as the Earth moving away from something adds to the rate at which it is...

how can you tell whether the interference fringes are moving in or out as you change the distance between the mirrors by rotating the knob clockwise or counterclockwise. say if the circular fringes are moving toward the center of the screen than in what direction the knob is being rotated. my...
