There is a lot written about interference, and, at first sight, this important natural phenomenon seems to have been studied completely enough. However, this is far from the case. For clarity, we simplify the pictures and show only node lines. Let us consider a case, when phase shift of the oscillators is zero for any velocity. The sources are coherent.
Deformation is obvious.
Appearance of an additional node line indicates deformation of the pattern. Let us consider another case in which, as velocity increases, the phase shift grows. For the time being, we do not discuss the reason for the phase shift, this is not a simple question, but we can ascertain that the phase difference changes automatically. Having spent energy increasing the phase difference, we note that an inverse process does not occur and deformation of the interference pattern is absent. Moreover, the braking reaction is absent too, and any attempt to brake the motion causes reaction of another kind called inertia.
