Why must initial focusing of an object be under the low power objective and not under the high power objective?
Low power objective is like our eye if we want to see we can just see normally but if we want to see something very small but want to see properly at that particular part then we always go for some lens of something powerful. That's the same thing when we want to know something deeply we go for high power microscope to read a more detailed study of a particular part of object under the microscope.
What is the name of the adjustment knob that moves the body tube for focusing with the high-power objective lens?
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.
When focusing a specimen you should always start with which objective?
You should start focusing with the lowest magnification objective, typically the 4x objective. This allows you to locate and center your specimen before moving to higher magnifications.
What should you do when viewing a specimen under highpower if you completely lose the focus?
If you completely lose focus while viewing a specimen under high power, you should first move the fine adjustment knob in both directions to try and regain focus. If that doesn't work, switch back to a lower magnification objective lens, refocus the specimen, and then switch back to the high power objective to try focusing again.
What happens to the depth of field as your move from low power to high power?
As you move from low power to high power, the depth of field decreases. This means that at high power, the area in focus becomes smaller and more limited compared to low power. This is due to the increased magnification at high power which results in a shallower depth of field.

Why is coarse adjustment knob not commonly used when focusing under high power objective?
The coarse adjustment knob moves the objective a lot while the fine adjustment knob moves it just a little, so using the coarse knob under high power can cause the objective to hit the slide and potentially damage the slide or the objective. The fine adjustment knob provides more precise control for focusing under high power, allowing for better clarity and accuracy.
Why it is advised to use the fine adjustment knob when you're focusing under high power object?
The fine adjustment knob allows for more precise focusing adjustments under high power, where the depth of focus is much shallower. This helps in achieving sharp and clear images when observing fine details of the specimen. The coarse adjustment knob may be too sensitive and lead to overshooting the focus point under high magnification.
Why should you never use a course adjustment knob on High power?
Using the course adjustment knob on high power can cause the microscope to move too quickly, potentially damaging the specimen or the objective lens. It is better to use the fine adjustment knob on high power for precise focusing.
The coarse adjustment knob on a microscope should never be used with the?
The coarse adjustment knob on a microscope should never be used with the high-power objective lens. This can cause damage to both the lens and the slide being viewed. Instead, it is best used with the low-power or scanning objective lens for initial focusing.
What are the dangers of using the coarse-adjustment knob when focusing under high power?
Using the coarse-adjustment knob under high power can result in the objective lens crashing into the slide, damaging both components. It can also cause the specimen to go out of focus quickly and potentially harm the quality of the image obtained. It is best to use the fine-adjustment knob for precise focusing under high power to avoid these risks.
Why is it important to focus specimens under the Low Power Objectve before observing it under the High Power Objective?
It allows you to center the specimen, and if it is set up correctly, then when you switch objectives it should still be there and only need fine focusing. It also reduces the chance of crushing the specimen and/or breaking the slide or the lens as the LPO is further away from the slide than the HPO.
Why shouldn't you use the course adjustment knob when viewing the specimen under high power?
You shouldn't. You can cause the high objective to smash into the surface of the slide and crack it. Always use the fine adj. for high power and if you cannot get the high power in focus, reverse out to low again and do it over. Ideally, if you are in focus on low, you should be in focus at medium (may have to adjust a small amount) and if you are in focus under medium, when you swing the high power obj. into place, it should be in focus as well (may need a fine tune). Always reverse out and start all over again if you cannot focus it under high power. Deja Was Here
Which part of the microscope is used to bring the image of an object on the slide into focus when under the high power objective lens?
The fine adjustment knob is used to bring the image of an object on the slide into focus when under the high power objective lens. This knob allows for precise focusing by making small adjustments to the distance between the objective lens and the specimen on the slide.
How dows the procedure for using the microscope differ under high power as opposed to low power?
When using a microscope under high power, you typically start by locating the specimen using the coarse adjustment knob on low power before switching to high power for a more detailed view. Under high power, you may need to use the fine adjustment knob more delicately to focus due to the increased magnification. Additionally, the field of view is smaller under high power compared to low power.
What is the name of the adjustment knob that moves the body tube for focusing with the high-power objective lens?
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.
What is the difference between the field of view under high and low power?
You can see less under high power because it focuses on a smaller part of the specimen, but in more detail than low power.
