Monochromatic light of wavelength λ illuminates a pair of thin parallel slits of width a separated by a distance d at normal incidence, producing an interference pattern on a distant screen. a) (10 points) Explain two modifications to the experiment which would cause the maxima (bright spots) of the diffraction pattern to move away from the center. b) (10 points) Explain two modifications to the experiment which would cause the minima (dark spots) of the interference pattern to move towards the center.
