The figure below shows the result of a double-slit diffraction experiment with light of wavelength 696 nm. The pattern is closely spaced bright and dark fringes. Only the central portion of the pattern is shown. Except for the missing spots, the bright spots are separated by a distance of y = 1.75 mm. The pattern is observed on a screen that is 3.55 m from the slits. How far apart are the slits (in mm)?

In a double-slit diffraction experiment, two slits of width 12.3 × 10-6 m are separated by a distance of 31.7 × 10-6 m, and the wavelength of the incident light is 578 nm. The diffraction pattern is viewed on a screen 4.20 m from the slits. Assume IP is the intensity at a point P, a distance y = 75.6 cm on the screen from the central maximum. Which of the following best describes where the point P is on the double-slit interference pattern? The point P is between the m = 18 maximum and the m = 19 maximum. The point P is between the m = 9 maximum and the m = 10 maximum. The point P is between the m = 10 maximum and the m = 11 maximum.

In a double-slit diffraction experiment, two slits of width 13.8 × 10-6 m are separated by a distance of 25.4 × 10-6 m, and the wavelength of the incident light is 692 nm. The diffraction pattern is viewed on a screen 5.32 m from the slits. Assume IP is the intensity at a point P, a distance y = 80.1 cm on the screen from the central maximum. Find the ratio of the intensity at P and the intensity at the center of the diffraction pattern (I0), IP/I0.
