Monochromatic visible light of frequency 5.27x1014 Hz falls on a double slit separated by 72.9 µm, creating a diffraction pattern on a screen 7.45 m away. Find the number of maxima that will appear on the screen, assuming the screen is large enough. HINT: The answer must be an integer. If you calculate that there can be 349.889 maxima, your answer is 349, not 350.
