Single slit diffraction pattern P5/Section V-1a: Diffraction from a single slit Use the setup shown in the figure above. Use a single slit with width W = 0.04 mm. Use L = 200 cm. Place a paper sheet on the screen and trace the diffraction pattern shown in the figure below (page 2a) laser θ L Single slit Optical bench (top view) screen

The minima in intensity of the diffracted light occur at for = 1, 2, 3,. .. If we plot versus n we get a straight line with slope If we solve for we get: n n I nL xn W x L S W W λ ± ± = exp exp Compare with the manufacturer's value of = 0.04 mm.
