A student is observing a slide of blood cells by using the low-power objective of a light microscope The cells are too small to examineso the student switches to the high-power objective The cells?
magnification.
What are the advantages of using low power objective for initial viewing?
To locate the exact site in the microscope field that you want to magnify.
When using a microscope how much larger than normal does an object appear with lower power objective?
Not all microscopes have the same magnification for the lower power lens.
When using a microscope with a 10x ocular and the 40x objective plane what is total magnification?
400x
Will an object 1594 angstroms in diameter be visible with the light microscope using the 100X objective?
yes it is.

What is the BEST procedure for focusing a compound light microscope?
Begin by using the lowest power objective lens and then switching to the next highest power lens.
When using a microscope how much larger than normal does an object appear with lower power objective?
Not all microscopes have the same magnification for the lower power lens.
How many times larger will an object appear if the microscope is set on the high power objective?
This depends entirely on the microscope you are using. Typical high lenses are 150x to 250x, some to 400x.
Why important to start focusing the lowest power objective?
You use the low power objective lens first to get your sample centered in the field of view.
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 concentrates the light on the objective being observed when using the microscope?
Condenser
What are the steps used to focus a microscope on high power?
First focus the microscope on the lowest objective using first the coarse djustment knob and then the fine adjustment knob. Once you have it in focus, move on and do the same for the next highest objective. Continue this process until you reach the highest objective and focus it in the same fashion.
