Chapter 27, Problem 10OQ

A Fraunhofer diffraction pattern is produced on a screen located 1.00 m from a single slit. If a light source of wavelength 5.00 × 10⁻⁷ m is used and the distance from the center of the central bright fringe to the first dark fringe is 5.00 × 10⁻³ m, what is the slit width?

1. (a) 0.010 0 mm
2. (b) 0.100 mm
3. (c) 0.200 mm
4. (d) 1.00 mm
5. (e) 0.005 00 mm
