Unformatted text preview: 2 m 0,1,2,3,. .. Single-Slit Diffraction For the drawing to the right, is measured from the center (m = 0) line. The vertical (y-axis) distance is y = L tan , where L is the distance from the slits to the screen. c.f. 2 / W Wsin m m 1, 2, 3,. .. Circular aperture Resolution n min 1.22 D D is the diameter of the aperture. y is the distance between the 2 light sources. L is the distance from the observer to the light sources. y tan sin L for small Diffraction Grating d sin = m m = 0, 1, 2, 3,...
