    Calculating wavelength of a 2D grating (different distances between slits)

    For my report I need a formula to calculate the wavelength with a multiple slit experiment. I have found: d sin(\theta) = m \lambda. However, for the experiment a two dimensional grating is used. The distance between the vertical slits are not the same as the distance between the horizontal...
