Question

Please solve and plot using MATLAB:

A monochromatic light that passes through a Incident slit produces on a screen a diffraction pattern light consisting of bright and dark fringes. The intensity of the bright fringes, I, as a function of 0 can be calculated by: πα where a asin θ , λ is the light wave length, a is the width of the slits. Make a 3-D plot (shown) that shows the rela- tive intensity 11/mas as a function of θ for -20°<θ 200, and a function of a/λ for 2 a/A 10. 0.8 02 0.4

Please solve and plot with MATLAB: Thank you
