After focusing on top of specimen what happens to the depth of focus as you turn the fine adjustment knob backward?
As you turn the fine adjustment knob backward after focusing on the top of the specimen, the depth of focus increases. This is because moving the fine adjustment knob backward moves the specimen away from the objective lens, which increases the distance between the specimen and the lens, resulting in a larger depth of focus.
Does resolving power increase with magnification?
If magnification increases ONLY, then resolving power does not increase. However, if the magnification increased while staying in focus (upgrading resolution and magnification with objective lense), shorter wavelengths are needed to stay in focus with increased magnification to yield the same high resolution as with previous objective lense, so this case, resolving power does increase.
Which of these is not true when changing magnification form low power to high power?
Increasing magnification changes the field of view, depth of field and amount of detail seen.
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.
Once focus is achieved at one magnification a higher power objective lens can be rotated into positon without fear of striking the slide true or false?
True. Once focus is achieved with a lower magnification objective lens, a higher power objective lens can be rotated into position without fear of striking the slide because the working distance between the lens and the slide increases with higher magnification lenses.
What happens to the depth of field as the magnification increases?
As the magnification increases, the depth of field decreases.
What happens to the working distance as the magnification increases?
As magnification increases, the working distance decreases. This is because higher magnification requires the lens to be closer to the specimen in order to focus properly. Therefore, as you increase magnification, you may need to physically move the lens closer to the subject to maintain focus.
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.

This is because moving the fine adjustment knob backward moves the specimen away from the objective lens, which increases the distance between the specimen and the lens, resulting in a larger depth of focus.
Why does the depth of field decrease when you increase the magnification?
When you increase the magnification, the depth of field decreases because magnifying the image makes it appear larger, which in turn amplifies any blurriness or focus issues. This means that any slight changes in focus become more noticeable, resulting in a shallower depth of field where objects appear out of focus more quickly.
What effect does an increase in magnification have on field of view depth of field and working distance?
An increase in magnification decreases the field of view, reduces the depth of field, and shortens the working distance. This is because higher magnification focuses on a smaller area with increased detail, leading to a narrower view, shallower depth of focus, and closer working distance.
Does resolving power increase with magnification?
If magnification increases ONLY, then resolving power does not increase. However, if the magnification increased while staying in focus (upgrading resolution and magnification with objective lense), shorter wavelengths are needed to stay in focus with increased magnification to yield the same high resolution as with previous objective lense, so this case, resolving power does increase.
What happens to depth of field as you increase the diameter of an iris diaphragm?
As the diameter of the iris diaphragm increases, the depth of field decreases. A larger diaphragm lets in more light, leading to a shallower depth of field with less of the image in focus. Conversely, a smaller diaphragm increases depth of field by letting in less light and making more of the image appear sharp.
As the magnification increases what decreases in a microscope?
As magnification increases in a microscope, the field of view decreases, meaning you can see less of your specimen at a time. Additionally, resolution may decrease slightly, impacting the clarity and sharpness of the image. It may also become more difficult to maintain focus as magnification increases.
Which of these is not true when changing magnification form low power to high power?
Increasing magnification changes the field of view, depth of field and amount of detail seen.
What is the relationship between the working distance of an objective lens and its magnification power?
As the magnification power of an objective lens increases, the working distance typically decreases. This is because higher magnification lenses have shorter focal lengths and need to be closer to the specimen to achieve focus. Lower magnification lenses have longer working distances, allowing more space between the lens and the specimen.
Which changing magnification from 10x to 40x the specimen disappears?
When the magnification is increased from 10x to 40x, the field of view becomes smaller and the depth of field decreases. This can cause the specimen to go out of focus or move out of the field of view, appearing to disappear. Adjusting the focus and position of the specimen may help bring it back into view at the higher magnification.
