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.

Compare the functions of the objective lens in a telescope and a microscope?
The objective lens in a telescope is designed to gather light from distant celestial objects to form an image for viewing. In contrast, the objective lens in a microscope is used to magnify small objects and focus light to create a detailed image for observation at close range. Both lenses play a crucial role in forming clear and magnified images for the viewer.
What is used for final focusing on a microscope?
The objective lens is used for final focusing on a microscope. It is located closest to the specimen and is responsible for magnifying the image and bringing it into sharp focus. Adjusting the fine focus knob allows for precise focusing of the specimen.
Why is it that the image under the low power objective become inverted?
The image becomes inverted under the low power objective due to the design of the microscope and the way light rays are refracted and magnified by the lenses. The inverted image is a result of the optics in the microscope system.
Which magnifies the image in a telescope?
The objective lens or mirror in a telescope magnifies the image by gathering and focusing light from distant objects.
How does refraction help a microscope?
Refraction in a microscope helps to bend light rays, allowing the objective lens to focus on a specimen and magnify it. By bending light through the specimen, the microscope can produce a detailed image of small structures that would otherwise be invisible to the naked eye.
What part of the microscope is used to bring the image into sharp focus?
The fine focus knob is used to bring the image into sharp focus on a microscope. This knob allows for precise adjustments to the focus of the image by moving the objective lens slightly closer or farther from the specimen.
Which knob is used to get a clear image on a microscope?
You use the Fine Adjustment Knob to give a very clear image on the microscope, mostly used on high power magnification.
Why is the e inverted in the microscope?
The "e" in the microscope is inverted by the objective lens to produce an enlarged, inverted image that can be further magnified by the eyepiece. This inverted image allows for better focus and resolution when examining specimens on a microscope slide.
Which part of the microscope will you adjust if the onion cell you are observing under the HPO is not clear?
You should adjust the fine focus knob to sharpen the image when viewing the onion cell under high-power objective (HPO) on a microscope. Rotate the knob gently to focus the specimen until the image appears clear.
What does the fine-adjustment knob do on a microscope?
The fine-adjustment knob on a microscope is used to precisely focus the image by making small adjustments to the distance between the specimen and the objective lens. It allows for fine-tuning the focus of the microscope to get a clear and sharp image of the specimen.
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.
How do to change the magnification of the microscope?
To change the magnification of a microscope, rotate the objective lens turret to switch to a different objective lens with a desired magnification level. You can also adjust the focus using the fine focus knob to ensure a clear image at the new magnification.
What objective brings a specimen into focus using a microscope?
The objective lens of a microscope brings a specimen into focus by adjusting the distance between the lens and the specimen. This is done by turning the focus knob to move the lens up or down, which changes the focal point and sharpens the image.
Which object is used to focus light in a light microscope?
The lens is the object used to focus light in a light microscope. The lens in a light microscope is typically found within the objective lens or the eyepiece, and it helps to magnify the image of the specimen.
What is the function of the objective in a 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 power must be in place when you first find an image in the microscope?
You should first use the lowest power setting of a microscope to find an object and then center it within the viewing area. Then, when you switch to the next higher magnification, your target should still be close to the center and easier to find and focus on.
What is used to focus when using the scanner and low objective?
When using the scanner and low objective on a microscope, you should use the coarse focus knob to bring the specimen into approximate focus and then use the fine focus knob to achieve a sharp image. Adjusting the height of the stage may also be necessary to fine-tune the focus.
