An individual's eye pupil changes from a diameter of 1.5 mm to 3.5 mm as the illumination is increased. By what factor does the minimum angle of resolution change?
 a. 2.0
  c. 0.43
  b. 2.3
  d. 0.65

Question 2

A microscope has an objective lens with an aperture of diameter 0.60 cm where a monochromatic light source of wavelength 580 nm is used to illuminate the object. It is determined that the minimum angle of resolution is 1.18  10-4 rad. If the illuminating source were replaced by a source of wavelength 700 nm, what would the minimum angle of resolution now become? (1 nm = 10-9 m)
 a. 0.58  10-4 rad
  c. 0.85  10-4 rad
  b. 1.4  10-4 rad
  d. 1.2  10-4 rad
