5. (20 points) Light of wavelength k and frequency f passes through a single slit of width a. The diffraction pattern is observed on a distant screen located a distance x from the slit. Describe how the following changes affect the width of the central maximum. In each case, you must justify your answer. Recall: c = If. a.) (4 points) You decrease the slit width a b.) (4 points) You decrease the frequency f of the light. c.) (4 points) You decrease the wavelength of the light. d.) (4 points) You decrease the distance x to the screen. e.) (4 points) You perform the experiment underwater (n - 1.33). Recall: A/n
