What is the proper procedure for focusing the microscope?
start with the lowest objective then adjest your focus. After, switch your objective if needed going from lower to higher
Is it more desirable to increase or decrease light when changing to a higher magnification using a compound microscope?
It is more desirable to increase light when changing to a higher magnification using a compound microscope as the lens require more light. With proper lighting , it is easier to see specimen details as the lens aperture decreases with higher magnification.
What is the first magnificationused to look at a slide?
You start with the lowest magnification. Once you have found the specimen and focused it, you can move it to the next higher magnification. It should still be in focus, although you might need to use the fine adjustment.
How do you measure with a microscope?
The vernier adjustment is numbered. Go to the lowest point in the object you can focus on. Note your vernier setting. Adjust to the highest point you can focus on. Subtract the lower number from the higher and you get depth.

What is the function of the higher power objective on a microscope?
To increase the magnification of the specimen so you can see more detail.
What is the operation of a microscope?
fisrt,put the specimen into focus using a lower power lens, then switch to a higher power lens, if needed.

What is the procedure for the operation of a microscope?
First put the specimen into focus using a low power lens, then switch to a higher power lens if needed.
Why would a technician need to use a microscope with a high magnification?
It depends on what the specimen is. If for example - the specimen is a person's finger-print, then low magnification is sufficient. However - if the specimen is a sample of blood, a higher magnification would be needed to show individual blood cells.
When using the high power objective which focus knob do you use?
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.

What is microscope parfocalization?
Parfocal microscopes are made so you don't have to refocus when you change between magnifications. Having a parfocal microscope is convenient and is easier on the eyes.

It is more desirable to increase light when changing to a higher magnification using a compound microscope as the lens require more light. With proper lighting , it is easier to see specimen details as the lens aperture decreases with higher magnification.
What are magnification amounts on a microscope?
The magnification amount on a microscope refers to how much larger an object appears when viewed through the microscope compared to the naked eye. Microscopes typically have adjustable magnification levels, commonly ranging from 40x to 1000x or higher. Higher magnification allows for greater detail and resolution of the specimen being observed.
