Vertical Michelson Morley Experiment 11 15 2010 Frank G Pearce

An interferometry experiment conducted in the vertical plane to test the results of the Extended Michelson-Morley Experiment conducted by Mr. Martin Grusenick of Germany, The results demonstrate that Mr. Grusenick's experiment is flawed in that it produced erroneous fringe pattern shifting as a result of strain on the interferometer breadboard and optical components.

try the patterns lines perpendicular(90°) to the rotation speed. You are not repeating the experiment at all!!! Look his video. Thanks.

Hello Subspace4d - The orientation of the fringe lines does not affect the results. One can easily adjust the end mirror(s) to produce vertical or horizontal fringe lines. That is, the image on the screen is changed, but not the results. If you do not believe my response, then you can certainly verify this with Mr. Grusenick. His fringe lines will march in any image orientation you prefer and will move at the same rate.

Thank you. Frank Pearce

@Powerpak8 In fact it does. Please do the other experiment with perpendicular interference lines and post the video. Else your result is useless. Thanks!

OK, Subspace4d, I have reconsidered your request since I know that many people will not believe my statement, only the video. So, I will reluctantly re-assemble the interferometer, having torn it down after the last test run, and I will film it to show you that there is no difference in the orientation of the fringe pattern on the viewing screen. I shall post this within 48 hours. Frank Pearce

The follow-up experiment is at youtube.com/watch?v=iJodqg5XPd­k When the fringe pattern is rotated, the recombined light beams pass through the diverging lens at a slightly different spot, thus the lines are not as straight as before image rotation. However, make no mistake about it, these are actual fringe lines in the same orientation as the Grusenick experiment. The slight motion in the fringe pattern occurs at the same points as before image rotation. There is no difference. Frank Pearce

@Powerpak8 Thanks!!!
