Hello,
Two waves originated from point A and point B, waves are 'velocitydirectiondependent', can be treated as 'vectors', it took t2 time for the wave from point B to reach A, and it took time t2 for the wave from point B to reach A. Given the fact the two vectors have the same 'magnitude', and only the t1 and t2 are known is there a way to calculate delta velocity? A>>>>>>>>>>> B, in t1 time B>>>>>>>>>>> A, in t2 time Distance between A and B is constant, and only known variables are t1 and t2, is there a way to calculate Δv? thank you!

If the distance from B to A is d, then the first wave, taking t1 to go from B to A, has speed d/t1. The second wave, taking t2 to go from B to A, has speed d/t2. The "[itex]\Delta v[/itex]" is d/t1 d/t2= d(t2 t1)/t1t2.
If you do not know the distance from B to A, then you cannot calculate [itex]\Delta v[/itex].
