,What does the term "resolving power" refer to in microscopy?
✔✔Resolving power refers to the ability of a microscope to distinguish two points as separate.
What is the purpose of using immersion oil in microscopy?
✔✔Immersion oil increases the resolving power and allows higher magnification without losing
clarity.
What is the magnification of the high-power objective lens on most compound microscopes?
✔✔The high-power objective lens typically has a magnification of 40x or 50x.
What is the purpose of the coarse focus knob on a microscope?
✔✔The coarse focus knob is used to bring the specimen into general focus by adjusting the
distance between the objective lens and the stage.
What is the role of the fine focus knob on a microscope?
✔✔The fine focus knob is used to make fine adjustments to the focus after using the coarse
focus knob.

, What does the term "field of view" refer to in microscopy?
✔✔Field of view refers to the area visible through the microscope lens at a given magnification.
What is the function of the mechanical stage on a microscope?
✔✔The mechanical stage holds the slide and allows for precise movement of the specimen.
What is the significance of using a brightfield microscope in microbiology?
✔✔A brightfield microscope is used to view stained specimens by using light that passes
through the sample.
What does "depth of field" mean in relation to microscopy?
✔✔Depth of field refers to the thickness of the specimen that is in focus at one time.
What is the purpose of adjusting the light intensity on a microscope?
✔✔Adjusting the light intensity ensures proper illumination of the specimen for clear viewing.
What is the function of the arm on a microscope?
✔✔The arm supports the body tube and connects the ocular lens to the base of the microscope.
