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.
What does the fine-adjustment knob do on a microscope?
The fine-adjustment knob moves the body tube slightly to bring the image into sharper focus.
Instrument that produces an enlarged image of an object?
microscope
What are the steps to focus a microscope?
Depending on the microscope the steps differ but assuming you are using a light microscope (the only microscope you will use before university). The microscope must be set to the lowest magnification with the stage set as far way as possible (the platform the sample is held on). Then using the coarse focus (the larger knob) bring the stage towards the lens while looking though the eye piece when the sample comes into focus use the fine focus knob (the smaller knob) to bring the image to optimum focus. When this is achieved increases the magnification (by changing to a stronger lens) and using fine focus continue to focus the image and keep repeating the steps till a max focus is achieved. If more information is need let me know as there are more complicated techniques but this should be enough for before a university level depending on what country you are in.
What has a objective lens that creates an image of the object that is enlarged by the eyepeice?
microscope
What part of the microscope is used to bring the image into sharp focus?
For the adjustment of focus, you would have to use the Fine-adjustment knob located on the left and right sides of the microscope arm.

What the most major difference between telescope and microscope?
A telescope must gather large amounts of light from a dim, distant object; therefore, it needs a largeobjective lens to gather as much light as possible and bring it to a bright focus. Because the objective lens is large, it brings the image of the object to a focus at some distance away
What does the fine-adjustment knob do on a microscope?
The fine-adjustment knob moves the body tube slightly to bring the image into sharper focus.
What is the function of the coarse focus knob of the microscope?
To focus the image of the specimen
What job does the focusing knob do on a microscope?
The final focus? Its used for final focusing of the specimen.
Instrument that produces an enlarged image of an object?
microscope
How do you improve the quality of image under light microscope?
by focus and magnification
When do you use fine focus and the coarse focus knobs?
The fine focus knob is used to bring an object into fine focus, while the course focus knob is used to bring an object into approximate focus. The course focus knob should only be used on the low-power and scanning objectives of the light microscope. Using it on the high power microscope is okay, but you should be very careful. It is no recommended to use the course adjustment knob on the oil-emersion objective as it is so close to the stage and could lead to a potential break in the slide. Fine focus adjustment knob is useful to bring out the fine details in the specimen on your slide. Can be used on any of the objectives, but most receptive on the high-power and oil-emersion objectives.

What is the objectives 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.
