In MMs work it was assumed that the mirrors were held in a rigid relationship and so differences in light speed along the orthogonal arms would show up as a phase shift.

NettetThe Michelson interferometer is one of the key experiments in modern physics when it comes to the topic of interference (Box 1). Experiments using interferometry have a high historic relevance as well as uses in current areas of research (quantum erasers, gravitational wave detection) and are used in higher education. Because of the high … NettetPhysics questions and answers. (1) Imagine that the LIGO experiment used a normal Michelson interferometer that had no Fabry-Perot cavities in it. The two arms of the interferometer begin with the same length \ ( L \), but then something happens (gravitational wave passes by!) to cause one of them to change by an amount \ ( \Delta …
