    ok, I am doing an experiment where i measure the speed of a water wave in a wave tank (see pic) and the fourmla i have to calculate the speed needs the wave length, so far i have justassumed that wavelength was the length of the tank, and that give good results which correspond to some results i generated using the same formula
    (c = sqrt((gλ / 2 pi) * tanh (2 pi d / λ)).
    But i cannot explain why the wave length is just the length of the tank :confused: Any one got any ideas?!

    eq set up ^
