Light of wavelength 525 nm passes through two slits separated by 0.500 mm and produces an interference pattern on a screen 7.80 m away. The intensity at the central maximum is I0.
 
  What is the distance on the screen from the center of this central maximum to the point where the intensity due to double-slit interference has fallen to 1/2 I0?

Question 2

In a double slit experiment, the intensity of light at the center of the central bright fringe is measured to be 6.2 W/m2.
 
  What is the intensity halfway between the center of this fringe and the first dark band, assuming that the small-angle approximation is valid? A) 6.2 W/m2
  B) 3.1 W/m2
  C) 4.7 W/m2
  D) 1.6 W/m2
  E) 0.12 W/m2
