In a double slit experiment having 500 nm light, the slits each encompass a width of 0.1mm.
i) When the interference fringes are 5mm apart on the screen that is 4m from the slits, find out the separation of slits.
ii) Find the distance from the center of pattern to the first diffraction minimum on one side of the pattern?
iii) Determine the number of interference fringes which will be seen in the central maximum in the diffraction pattern?
