In a double slit experiment, the ratio of slit separation to the slit width is 1.7 (three bright fringes in the central peak). If the slit separation is increased by a factor of four, keeping the slit width the same, how many interference fringes will now fit in the central diffraction peak? 6 13 5 12

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.
