Download Solution PDFThe correct answer is: Low-power objective lens.
Key Points
- The coarse adjustment knob is used to quickly move the stage of the microscope up or down.
- This quick and imprecise adjustment is ideal for the low-power objective lens, where the risk of collision between the lens and the slide is minimal.
- It allows the observer to quickly bring the specimen into the general area of focus.
- However, for higher magnification lenses, the fine adjustment knob should be used to avoid damaging the slide or the lens.
Additional Information
- A microscope is an instrument used to see objects that are too small for the naked eye.
- Objective lenses are the primary lenses in a microscope that gather light from the sample, magnify the image of the sample, and project it into the eyepiece.
