The coarse adjustment knob may move the lens too far too fast and the slide may crack and/or the object be squashed. Using the fine adjustment lens will bring the object into focus much more accurately. In addition, the coarse adjustment knob adjusts in too great a quantity. The fine is less responsive so its easier to adjust at high magnification.
You would use the coarse adjustment knob to quickly bring the specimen into view, and then the fine adjustment knob to focus on the details of the specimen.
You would use the coarse focus knob to focus on low power. Turn the coarse focus knob clockwise to bring the specimen into view and then fine-tune using the fine focus knob.
10x4=40 power its the farthest and shall give you farther view if you would like you can move closer to 10x10= 100 power or the highest 10x40 400 power
After switching the microscope from low to high power, you may need to readjust the diaphragm to regulate the amount of light entering the lens. This adjustment helps maintain optimal image brightness and clarity at different magnifications. Start by opening the diaphragm fully and then gradually close it until the image is clear and properly illuminated at high power.
An energy source that never runs out would be called: Impossible. There is no such thing as an energy source that will never run out otherwise it would break the Laws of Thermodynamics and we would all be in big trouble. Renewable energy sources are based on things like wind power, solar power which we expect will last longer than the human species.
The adjustment knob that moves the body tube for focusing with the high-power objective lens is called the fine focus adjustment knob. It allows for precise adjustments to bring the specimen into sharp focus at high magnifications.
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.
The coarse adjustment knob controls the stage's vertical position in relation to the objective lenses. If improperly used under high power, it can damage the objective lens or the slide due to the rapid movement.
It would be difficult to focus, a small movement would make a big difference
You would use the coarse adjustment knob to quickly bring the specimen into view, and then the fine adjustment knob to focus on the details of the specimen.
The fine adjustment knob on a microscope allows for precise focusing of the image at high magnification by making small adjustments to the distance between the objective lens and the specimen. It is used after rough focusing with the coarse adjustment knob to bring the image into sharp detail.
The fine adjustment knob is used with the power objective on the microscope. Since the objective is already at the highest objective possible for that microscope, using the coarse adjustment knob would focus to much on the object making the details harder to read. Using the fine adjustment knob, you are able to see the fine details within the object or organism you are studying. The higher the power, the finer the knob and the lower the objective, the coarser the knob and objective.
You would use the coarse focus knob to focus on low power. Turn the coarse focus knob clockwise to bring the specimen into view and then fine-tune using the fine focus knob.
Of coarse they would, we humans can survive weeks without food as long as there is an intake of water.
Coarse means Rough. E.G Sand paper is very coarse maybe if you roughhouse with your friends that would be an example of coarse. main definition is ROUGH
on a high powered setting the course adjustment knob would move the slide up and down too quickly to be able to work properly. the course adjustment knob should only be used on low power settings
If you had to make 2 adjustment to your sleep schedule, what would it be and why
