When light with a wavelength of 425 nm uniformly illuminates a single slit, the central bright fringe, observed on a screen located 0.630 m from the slit, has a width of 0.0166 m. What is the width of the slit? A)1.61 × 10^-⁵ m B)3.23 × 10^-⁵ m C)4.84 × 10^-⁵ m D)8.07 × 10^-⁵ m E)1.09 × 10^-⁴ m

The width of the central bright fringe is given by the formula: width = 2 * (wavelength * distance to screen) / slit width. Solving for the slit width gives: slit width = 2 * (425 nm * 0.630 m) / 0.0166 m = 3.23 × 10^-5 m.
