5. A monochromatic light with wavelength = 500 nm is used to illuminate a single slit. Assume that the width of slit isD= 0.5 mm. The distance between slit and

the observation screen is L. (20 points) (a) Please sketch the light intensity distribution for L < 0.5 mm. (b) Please skeich the diffraction pattern at the location L= 10 mm. (c) Please sketch the light intensity distribution for L = 5000 mm.(d) What is the full width of the central spot for L= 5000 mm. (d) What is the full widih ofthe central spot for L= 5000 mm,
