Which of the following is a correct procedure for the operation of a microscope? First, put the specimen into focus using a low power lens, then switch to a lower power lens if needed.Remove and add slides while the high power lens is selected.First, put the specimen into focus using a low power lens, then switch to a higher power lens if needed.Use the fine focus knob with the low power lens and use the coarse focus knob with the high power lens
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.
when they want to see the inside of the cell.when you use a electron microscope the cell is going to die.
Becoz they r too smaller than bacteria and they examined in electron microscope(TEM&SEM)
The lens that you should use to first look at a slide on a microscope is a low power lens then move on to a higher power for more clarity.

It is the Coarse Adjustment, but only use it on Low Power.
A low power objective in a microscope is a Small Lens with Low Magnifying Power. A microscope head with two eyepiece lenses, one for each eye. Generally this term is used in describing a high power (compound) microscope. With a low power microscope we say "stereo" head because, unlike the compound microscope, the stereo has a separate objective lens for each eyepiece lens, producing two independent paths of light, one for each eye. In the compound microscope with a binocular head, there are two eyepiece lenses but still only one objective lens and you will not get stereo vision. Hope this helps.
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.
remove the slide,return the low-power objective, use lens paper to clean the stage of microscope and the lenses
low power means we observed specimen at 40x and for more clear result we go to high resolution wich is 100x with the use of oil emmersion
start with the low power objective
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
electric microscope
You would use low first so you can see where it is and then you would center it and make it on the edge of the pointer. Then go to medium;center the object;go to high; center then your done!!! a 7th grader
