In a single - slit diffraction experiment, monochromatic light of wavelength 565 m is passed through a slit 0.360 mm wide, and the diffraction pattern is observed on a screen 5.78 m from the slit. The intensity at the center of the pattern is Iâ‚€ . What is the ratio of the intensity at the center of the pattern to the intensity at a point 3.38 mm from the center of the diffraction pattern ( ( : I/Iâ‚€ } ?
