A 1.0-cm-diameter microscope objective has a focal length of 2.8 mm . It is used in visible light with a wavelength of 550 nm.
Part A.) What is the objective's resolving power if used in air? (answer is to be in nanometers)
Part B.) What is the resolving power of the objective if it is used in an oil-immersion microscope with n oil = 1.45? (Answer to be in nanometers). Please Show the steps in solving.
