A single-slit diffraction pattern is produced from a light source of wavelength 580 nm. The light goes through a single slit and onto a screen 1.0 m away. The first dark fringe is 5.8 mm from the central bright fringe. What is the slit width? (1 nm = 10-9 m)
 a. 0.12 mm
  c. 0.081 mm
  b. 0.24 mm
  d. 0.10 mm

Question 2

Light of wavelength 610 nm is incident on a slit of width 0.20 mm, and a diffraction pattern is produced on a screen that is 2.0 m from the slit. What is the distance of the second dark fringe from the center of the central bright fringe? (1 nm = 10-9 m)
 a. 1.4 cm
  c. 0.68 cm
