Final answer:
Magnification and resolution are two important concepts in microscopy. Parfocal and parcentral are terms used to describe the arrangement of lenses in a microscope.
Step-by-step explanation:
Magnification and resolution are two important concepts in microscopy. Magnification refers to the ability of a lens to enlarge the image of an object, while resolution refers to the ability to distinguish two separate points or objects. A high-resolution image appears sharp and clear, while a low-resolution image appears fuzzy. The factors that affect resolution are wavelength and numerical aperture.
Parfocal and parcentral are terms used to describe the arrangement of lenses in a microscope. Parfocal means that when you switch between objectives, the sample remains in focus, while parcentral means that the object remains centered in the field of view when switching between objectives.
