Explain the difference between Fresnel diffraction and Fraunhofer diffraction. Comment on the behaviour of the fields and how they interfere in each zone. Is there a sudden or smooth transition from the Fresnel zone to the Fraunhofer zone? (3 marks) Describe how you would write a Python code that could model the far-field diffraction pattern of a rectangular aperture source. Note: Precise syntax is not required, just a description of the steps to be taken in the code. (4 marks) State the analytical function that results from solving the far-field problem of a one- dimensional slit with a width of 2a, and explain each term in the function. (3 marks) For a one-dimensional slit with a width of 0.2mm illuminated with light of wavelength 4 microns, calculate the position of the first null and first secondary maximum on an observation screen 10 m from the source.
