What part of the microscope should you used to focus the image when using high power objective lens?

First of all, one should never call it high power, it is morecommonly called the "high objective", yet that is not what this question is asking.
To answer the question:
You use the fine adjustment knob. This knob should be located near the coarse adjustment knob, on the opposite side of the microscope (at the same height as the coarse adjustment knob), or even as a separate knob protruding from the coarse adjustment knob. The fine adjustment knob is smaller in size.
You should never, ever use the coarse adjustment knob under the high objective, you could scratch the microscope slide, cover slip, high objective lens, or in a worst case scenario break the high objective lens.

Which magnifies the image in a telescope?
The objective lens
How do you improve the quality of image under light microscope?
by focus and magnification
What is microscope parfocalization?
Parfocal microscopes are made so you don't have to refocus when you change between magnifications. Having a parfocal microscope is convenient and is easier on the eyes.
Does a microscope form a real image?
Actually, the image doesn't form in the microscope. The image forms on your retinas. The microscope focuses light in such a way that it comes together correctly on your retinas.
What is the ability to see details in a microscope called?
The depth of field is the part of a specimen that is in sharp focus; the depth of field decreases as the NA increases. The depth of focus on the other hand is the magnified image in focus on the film plane; depth of focus decreases as magnification increases.

Explain how focussing occurs in a microscope?
To focus the image, you have to move the object you are studying closer to or farther from the objective lens.
Why is the objective lenss called the objective lenss on the microscope?
The objective lenses are the optical element that gathers light from the 'object' being observed and they focus the light rays to produce a real image.
What is the function of objective the microscope?
The objective on a microscope is comprised of a tube and one or more lenses, and may include a mirror as well. Its purpose is to gather and focus light, typically while magnifying the image, from the sample or object under study.

What does a high-power objective do on a microscope?
The high-power objective magnifies the image 4x.
What is the function of the wide angle objective lens on a microscope?
An objective lens gathers light passing through the specimen on the microscope and projects the image into the body of the microscope. Objective lens are closest to the specimen.
What is the function of the coarse focus knob of the microscope?
To focus the image of the specimen
What does objective lenses in the microscope do?
A compound microscope has two lenses - the eyepiece lens and the objective lens. the objective lens(which is a convex lens) collects light and brings it to focus, creating an image. The eyepiece lens is placed at the focal point(the point at which light rays meetafter passing thru the convex lens). Thus we are able to see the magnified version of the image.
