Locating dark fringes for Young's Double Slit Experiment
This CalcTown calculator finds the position of dark fringes on the screen for a Young's Double Slit Experiment.
note that these values are calculated under the assumption that y=0 for
central maxima. Also,n=0 for first dark fringe on the positive side and n=-1 for first dark fringe on the negative side, and so on.
