A microscope has an objective lens with an aperture diameter 0.60 cm. 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 present lens were replaced by one with an aperture of diameter 1.0 cm, what would the minimum angle of resolution now become? (1 nm = 10-9 m)
 a. 1.5  10-4 rad
  c. 0.71  10-4 rad
  b. 0.79  10-4 rad
  d. 1.8  10-4 rad

Question 2

Light with a wavelength of 450 nm shines through a lens with an aperture diameter of 0.85 cm. Use Rayleigh's criterion to determine the limiting angle of resolution. (1 nm = 10-9 m)
 a. 6.5  10-5 rad
  c. 9.2  10-5 rad
  b. 1.3  10-4 rad
  d. 3.0  10-9 rad
