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