Light of wavelength 589 nm is used to view an object under a microscope. The objective lens of the microscope is the lens that gathers light from the object being observed and focuses the light rays in order to form an image of the object. It acts as the aperture of the system, determining its resolution. In this case, the objective lens is circular, of diameter 0.95 cm. Assuming that the resolution of the microscope depends solely on the diffractive...
