Schematic diagram of a single-slit diffraction setup. Parallel light rays of wavelength \(\lambda\) enter from the left toward a slit of width \(a\). To the right, at a distance \(D\), a vertical screen displays an intensity pattern with a wide central maximum and smaller secondary maxima. A dashed central axis connects the slit to the center of the pattern, and a vertical dimension arrow marks the distance \(y\) from the axis to the second dark minimum above the center. No other labels or lines appear.
Single-slit diffraction setup with screen at distance \(D\).
Monochromatic light with a wavelength of \(\lambda = 600\text{ nm}\) is incident normally on a single slit of width \(a = 0.12\text{ mm}\). The resulting diffraction pattern is observed on a screen placed at a distance of \(D = 2.0\text{ m}\) from the slit. What is the distance on the screen between the center of the central bright maximum and the center of the second-order dark fringe?
