(i)[2.0]
Draw a labelled graph of intensity of diffracted light ($I$) versus angle ($\theta$) in the Fraunhofer diffraction experiment for a single slit diffraction.
Draw: Graph of intensity of diffracted light (I) versus angle (\theta) in Fraunhofer diffraction by a single slit
Must show: Central maximum with peak intensity I_0, Secondary maxima of decreasing intensity on both sides, Minima at \theta = \pm \lambda/a, \pm 2\lambda/a, \dots
