Light of wavelength 589 nanometer is used to view an object under a microscope. If the aperture of the objective has a diameter of 0.900 centimeter,
(a) Determine what is the limiting angle of resolution?
(b) If it were possible to use visible light of any wavelength, determine what would be the maximum limit of resolution for this microscope?
(c) Assume that water fills (n=1.33) the space between the object and the objective. Explain what effect does this have on resolving power when 589 nm light is used?
