A Young's double-slit apparatus is set up so that a screen is positioned 1.6 m from the double slits, and the spacing between the two slits is 0.0315 mm. What is the distance between alternating bright fringes on the screen if the light source has a wavelength of 630 nm? (1 nm = 10-9 m)
 a. 0.016 m
  c. 0.025 m
  b. 0.047 m
  d. 0.032 m

Question 2

 a. 1/2
  c. 1
  b. 1/4
  d. 2
