2. Light of wavelength 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 = f. a. You decrease the slit width a. b. You decrease the frequency of the light. c. You decrease the wavelength of the light. d. You decrease the distance x to the screen. e. You perform the experiment underwater (n = 1.33). Recall A, λ/n.
