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 different under high power as oppose 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.

What is the difference when observing a specimen under high power and low power?

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 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.
The fine adjustment knob is used to focus an image only on what power?
AnswerFine adjustment knobs can be used on any of the different power lenses. Fine adjusting knobs help in clarifying a partially focused image.
What precautions must be taken when using a microscope when it is in high power lens?
Because you are at the highest magnification, only turn the fine adjustment knob when you are using the high-powered objective lens, and not the coarse adjustment. Otherwise you risk getting your sample out of focus, and you will probably only be able to refocusby starting with the lowest power objective lens.
High power on microscope?
On a the microscope I use, the ocular (eyepiece) has a magnification power of 10x. The 'low' (or 'scanning') objective lens is 4x, the 'medium' has a power of 10x, and the 'high' has a power of 40x. Multiply the ocular by the lens you're using to get your 'total magnification.' TIP: Only use the coarse adjustment knob while on 'low' power, then use the fine adjustment. Why? If you use the coarse adjustment knob on 'medium' or 'high,' there's a good chance you'll crack your slide. -BugCrunch

What is the microscope said to be when the fine adjustment is the only thing needed to be used to focus when in the highest power?
I think it is parfocal
What is the lens that is used to find the specimen on a microscope?
You use the low power lens to find the specimen with a microscope. Once you have found the specimen on low power, you can switch to high power for greater magnification. Just be sure to use only the fine adjustment knobs for focusing on high power so the high power objective won't hit the slide.
