    what is the maximm and minima of a light wave
    is the maxima the peak
    and the minima the trough
    it makes little sense
    because if the minina = the trough,
    and that has the least intensity
    THEN
    why is the equilibrium 0
    dark fringes at equilibrium

    You are getting two things mixed up.
    The "dark fringes" maxima and minima are interference patterns caused by light waves adding together such that they combine constructively (peak to peak or trough to trough) or destructively, peak to trough. The maxima and minima of the pattern are not the peaks and troughs of the waves themselves, they are caused by the peaks and troughs of 2 waves adding together.
