A light source simultaneously emits light of two wavelengths, 480 nm and 560 nm, respectively. The source is used in a double-slit interference experiment where the slit spacing is a 0.040 mm, and the distance between double slits and the screen is 1.6 m. What is the separation between the m = 3 bright fringes of the two wavelengths as they appear on the screen? (1 nm = 10-9 m)
 a. 0.96 cm
  c. 0.64 cm
  b. 0.48 cm
