What many people do not realize is that in the root of all motion detection by means of sound or electromagnetic waves, be it by interferometry or direct wave length measurements, there is, invariably, the all important Doppler effect. Experimenters who conducted experiments in interferometry, which involve phase comparisons, resorted frequently to a naive analogy with boats in river flows to substantiate their calculations.That analogy does not take into account that the source and observer are moving together in the same direction. And that makes all the difference! Apparently, the prime importance of the Doppler effect has been consistently neglected. Thinking in terms of Doppler makes things easier!. So, let's, firstly, try to bring it back to its rightful stand.
