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

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
