Fringe separation y = D d . Single slit diffraction : For slit width a , screen distance D , a sin = m for the m th diffraction minimum. For small angle the distance form the center to the first diffraction minimum on one side is y min = D a . Circular aperture diffraction of diameter a : The first diffraction minimum is found at sin min = 1 . 22 a , or , min = 1 . 22 a for small ....
