If you use the coarse-adjustment knob to focus on an object with the high-power objective what problems will you encounter why?
Using the coarse-adjustment knob with the high-power objective can result in the objective lens getting too close to the slide, potentially damaging the lens or slide. This can also lead to the objective lens hitting the slide, causing a loss of focus and potential damage to both the lens and the slide.
Why is coarse adjustment knob not commonly used when focusing under high power objective?
The coarse adjustment knob moves the objective a lot while the fine adjustment knob moves it just a little, so using the coarse knob under high power can cause the objective to hit the slide and potentially damage the slide or the objective. The fine adjustment knob provides more precise control for focusing under high power, allowing for better clarity and accuracy.
Why should you never use the coarse adjustment knob on high power for a microscope?
Using the coarse adjustment knob on high power can potentially damage the microscope or the slide being observed due to the high magnification and close proximity of the objective lens to the slide. It is better to make coarse adjustments on low power to avoid hitting the objective lens against the slide.
Why should you never use the coarse adjustment on higher power?
Using the coarse adjustment on higher power can risk damaging the lens or the slide because the distance between the lens and the slide is very small. It can also cause the objective lens to hit and break the coverslip or slide. Finer adjustments should be made with the fine adjustment knob when using higher magnifications to prevent this.
Why shoukld you never use the coarse adjustment knob on high power?
Using the coarse adjustment knob on high power may cause the objective lens to come in contact with the slide, potentially damaging both the lens and the slide. It can also lead to misalignment of the optics, resulting in blurry images and potential damage to the microscope.

What happens if you try to use the coarse adjustment when the 10x lens is in place?
One thing that can happen if you use the coarse adjustment while the oil immersion objective is in place is that the slide will end up breaking. It is better to use the fine adjustment.
What happens if you move coarse adjustment knob away from you?
If you move the coarse adjustment knob away from you, the objective lens or stage will move downwards, increasing the distance between the specimen slide and the objective lens. This will result in the focus point moving further away from the specimen, leading to a blurry image.
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.
When is it inappropriate to use the coarse adjustment?
It is inappropriate to use the coarse adjustment knob when focusing on high-power objectives, typically 40x or higher, as this can lead to damage to the slide or the objective lens by bringing the stage too close to the lens. Instead, fine adjustment should be used for precise focusing at these magnifications. Coarse adjustment is suitable only for low-power objectives, where greater distances between the lens and slide are maintained.
Why should you never use the coarse adjustment on higher power?
Using the coarse adjustment on higher power can risk damaging the lens or the slide because the distance between the lens and the slide is very small. It can also cause the objective lens to hit and break the coverslip or slide. Finer adjustments should be made with the fine adjustment knob when using higher magnifications to prevent this.
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.
Which of the objectives comes closest to specimen and is most likely to break a slide if proper precautions are not taken?
The high power objective lense will most likely break the slide. You need to use coarse adjustment on the low power objective lens.
What happens when you try to use the coarse adjustment when the 10x lens is in place?
When using the coarse adjustment knob with a 10x lens in place on a microscope, you risk moving the stage too quickly and potentially crashing the objective lens into the slide. This can damage both the slide and the lens, leading to misalignment or breakage. It's generally recommended to use the coarse adjustment only with lower magnification lenses, such as 4x or 10x, and to switch to fine adjustment for higher magnifications.

Using the coarse adjustment knob on high power may cause the objective lens to come in contact with the slide, potentially damaging both the lens and the slide. It can also lead to misalignment of the optics, resulting in blurry images and potential damage to the microscope.
