Because if you use coarse adjustment, the body tube of the microscope (the part that moves up and down when you turn the knobs) will hit the microscope slide and cause the slide to break/crack. It moves the tube very quickly . You also run the risk of damaging the high power lens when it hits the slide. The fine adjustment only moves the tube a teeny tiny bit and very slowly so you don't have a great of a risk of damaging the slide or lens. The fine adjustment also helps to focus slowly so you don't miss the object you're trying to see.

How does the procedure for using the microscope differ under high power as opposed to low power?
use the fine adjustment knob to get a better view of what you are looking at.For low power you can use the coarse adjustment and fine adjustmentfor high power you should only use the fine adjustment because on high power, the objective lens is too close to the slide and using the coarse adjustment may scratch the objective lens.

6 How does the procedure for using the microscope differ under high power?
For low power you can use the coarse adjustment and fine adjustment for high power you should only use the fine adjustment because on high power, the objective lens is too close to the slide and using the coarse adjustment may scratch the objective lens.
Why should the fine adjustment knob be used only with the HPO?
The fine adjustment knob should be used only with the high-power objective (HPO) because it allows for precise focusing at high magnifications. Using the fine adjustment knob with lower-power objectives can result in the objective lens hitting the slide, potentially damaging both the lens and the slide.
What focus adjustment should you use to focus on the specimen under the high power?
When focusing on a specimen under high power, you should use the fine adjustment knob. The coarse adjustment knob is typically used only under low power to prevent damage to the slide or objective lens. The fine adjustment allows for precise focusing, which is crucial at high magnifications to achieve a clear and sharp image of the specimen. Always ensure that you start with the lowest power objective before switching to high power for safety.
Why cant the coarse adjustment knob be used on high power lenses?
The coarse adjustment knob is used for making major changes to the focus, and is therefore too inaccurate to use at high powers, where only a very fine adjustment can drastically change the clarity of the picture you see.
Why should you only use the fine adjustment knob when you are using high power?
The fine adjustment knob should be used with high power magnification because it allows for smaller, more precise movements of the objective lens. This helps to prevent damage to the slide and objective lens, as well as minimize the risk of crashing the objective lens into the slide.
Why should you only use the fine adjustment when the high power objective is in position?
Because if you use the coarse adjustment under high power, there is a greater risk that you will crack the slide on the microscope and damage it. The fine adjustment only moves the objective lense small amounts and very slowly, so there is no chance that you will damage the slide.
Why is it important to only use that adjustment knob on high power?
Using the adjustment knob on high power ensures that the fine adjustment movement is more precise and controlled, resulting in clearer and sharper image focus. This prevents damaging the microscope components by trying to focus on low power, where the knobs move the stage too quickly and could cause collisions.
Why is fine adjustment used for high power?
Fine adjustment is used for high power magnification in microscopes to precisely focus on the details of the specimen being observed. At high magnifications, even slight movements can cause the image to become blurry or out of focus. The fine adjustment knob allows for small, controlled movements of the objective lens to achieve sharp focus without over-adjusting. This is crucial for accurately studying fine structures and details in the specimen.
Why should the fine adjustment knob be use only with the hpo in microscope?
The fine adjustment knob should only be used with the high-power objective (HPO) in a microscope to achieve precise focusing without risking damage to the slide or the objective lens. Using coarse adjustment at high magnification can lead to the lens crashing into the slide, potentially breaking the slide or the lens. The fine adjustment allows for delicate, minor adjustments needed for sharp focus at high magnification. This ensures optimal clarity and detail while maintaining safety for the specimen.
Why is it dangerous to focus using the coarse adjustment knob for on a microscope when using high power?
Using the coarse adjustment knob can lead to the objective lens crashing into the slide, potentially damaging both the lens and the slide. This is particularly dangerous when using high power magnification as the lens is closer to the slide. It is safer to only use the fine adjustment knob when focusing at high power to avoid this risk.
