After focusing on top of specimen what happens to the depth of focus as you turn the fine adjustment knob backward?
If the fine focus knob is turned backwards the depth of the specimen decreases. When the knob is turned forward the depth of the specimen increases.
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.
A microscope that maintains focus when the objective magnification is increased is called?
parfocal
Which of these is not true when changing magnification form low power to high power?
The specimen should be in clear focus
When you increase your magnification what happens to your field of view on a compound microscope?
By increasing the magnification the focus is increasing on a particular area due to which the no of light rays which were before more on the entire slide is now decreased due to focusing (magnifying) hence the brightness decreases due to decreased in no of light rays present in that small area
After focusing on top of specimen what happens to the depth of focus as you turn the fine adjustment knob backward?
If the fine focus knob is turned backwards the depth of the specimen decreases. When the knob is turned forward the depth of the specimen increases.
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.

Why it is necessary to be able to focus on different depths on the microscope?
Each depth will show different parts of whatever you are looking at on the microscope. The focus improves when using the right depth and magnification.
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 the energy of seismic waves as the distance from the focus increases?
They start to get smaller
Why is necessary to focus with the fine adjustment in high magnification?
To bring a sharp focus.
What knob controls the adjustments of focus?
it could be either coarse or fine knob. coarse knob is used to focus image at higher magnification, while fine knob is used to focus on lower magnification
What magnifications do you use the fine focus?
All magnification
What are the the names of the parts of the microscope that change the magnification?
The names of the parts of the microscope that change the magnification is the coarse focus knob.
What wheel adjustment is used to sharpen the focus on high power magnification?
Couse focus knob
What is the maximum depth a deep focus earthquake can occur to?
what is the maximum depth of a deep-focus earthquake
A microscope that maintains focus when the objective magnification is increased is called?
parfocal
