SUMMARY
The discussion focuses on calculating the angle for the second dark fringe in a single-slit diffraction pattern with a slit width of 1.5 x 10^6 m. The correct formula to use is d sin(θ) = nλ, where n = 2 for the second dark fringe. The wavelengths provided are 425 nm and 650 nm, leading to the angles θ of approximately 16.46 degrees and 25.68 degrees, respectively. The initial answers given were incorrect due to the misinterpretation of the fringe order.
