Explanation:

The resolution achieved by a lens is a measure of its ability to distinguish between two objects in the specimen. The shorter the wavelengths of illuminating light the higher the resolving power of the microscope. The wavelength of visible light ranges from 400 to 700 nanometers. The limit of resolution for a microscope that uses visible light is about 300nm with a dry lens (in air) and 200 nm with an oil immersion lens. The numerical aperture (NA) is a measure of the ability of a lens to collect light from the specimen. Lenses with a low numerical aperture collect less light than those with a high numerical aperture. The higher-power objectives have a higher numerical aperture and better resolution than the lower-power lenses with lower numerical aperture.
