Question
Sodium light of wavelength 589 nm is used to view an object under a microscope. The aperture of the objective has a diameter of 0.90 cm. (a) Find the limiting angle of resolution for this microscope. (b) Using visible light of any wavelength you desire, find the maximum limit of resolution for this microscope. (c) Water of index of refraction 1.33 now fills the space between the object and the objective. What effect would this water have on the resolving power of the microscope, using 589-nm light?
