In all descriptions of the http://en.wikipedia.org/wiki/Michelson%E2%80%93Morley" [Broken] I know of, the two arms of the interferometer are at right angles to each other.(adsbygoogle = window.adsbygoogle || []).push({});

Does anyone know of an experiment which, just for completeness, tried other angles? If not, does anyone know of a reference with clear argumentation why it can be ruled out that other angles need to be tested?

Not that I expect a different result for non-right angles, but (mathematical) proof is all the while better than guesstimation.
