What three things have to be done before putting away a microscope?
first you turn magnification lens to lowest setting. second, you remove the slide you were looking at. third, you turn off or unplug the microscope.
Who discovered the simple microscope?
Short answer: Zacharias Jansen Long answer: Your question is not valid for 2 reasons: 1. You cannot "discover" something if it does not exist. You should be asking who invented it, not who found it laying around somewhere. 2. A "simple microscope" is not common terminology. Simple compared to an electron microscope? or simple compared to a compound microscope? What is typically referred to as just "microscope" is technically a compound microscope. A set of multiple lenses mounted in a desktop style that allows the compounding of magnification. A compound microscope is the standard microscope in any basic lab setting. Anything more "simple" than a compound microscope would not even really be a microscope, it would either be a telescope, or simpler than that is a magnifying glass (with a single lens) The inventor of the magnifying glass was: Roger Bacon The next step up is the telescope invented by: Zacharias Jansen The next step up is the "compound microscope" which was also invented by: Zacharias Jansen (this is the simplest form of what would be recognized as or named "microscope") If you wanted to go even "simpler" and define microscope as anything that magnifies, there were reading glasses around for thousands of years prior, and even "reading stones" which were lumps of polished glass used to magnify parchment in Egypt as far back as 7000 B.C. (inventor unknown). So it really depends on how you wish to refine your meaning of simple. The magnification of anything? There is no known inventor for reading stones, his name is lost to time. Or if you mean the first invented microscope that could examine things too small for a human eye to detect, that's a compound microscope. Thus if I am guessing your meaning correctly, you meant to ask this question: Question: Who invented the compound microscope? Answer: Zacharias Jansen
What is the function of the iris adjustment wheel?
Many microscopes have a rotating disk under the stage. This diaphragm has different sized holes and is used to vary the intensity and size of the cone of light that is projected upward into the slide. There is no set rule regarding which setting to use for a particular power. Rather, the setting is a function of the transparency of the specimen, the degree of contrast you desire and the particular objective lens in use.
What is a called when a Diamond is in a setting by itself?
A solo diamond setting is called a solitaire.
If the Moon is setting at 6 am the phase of the Moon must be?
If the moon is setting at 6am then it is a New Moon
Why is it important not to have the light intensity setting too high on a light microscope?
It could burn and melt the specimen
Explain how to prepare a specimen for viewing in a electron microscope?
For a scanning electron microscope, the most commonly used type of EM, there is no need to do anything other than stick it to an electrically conducting pad. If the sample is particularly insulating, it may be worth coating it with a very thin gold layer to prevent the specimen from charging up with electrons from the beam (this would blur the image) For a transmission electron microscope, the specimen is most commonly encased in epoxy resin before being sliced into thin enough slices that the electron beam can pass through. The sample is then placed on a fine copper grid before being placed in the microscope.
What should be done before viewing through a compound microscope?
you should make sure the microscope is clean and ready. and that it is set on the right setting. i actually have no clue . suckerrr
What does the fine adjustment knob on a microscope do?
The fine adjustment, the two little knobs on both sides of a compound microscope, is rotated to move the body tube down or the stage up in tiny distances to help you focus in HIGH power.The fine focus knob is geared with a different ratio than the coarse knob to "fine tune" your focus. It allows for tiny adjustments to the focus setting, rather than larger ones.

What are the two types of diaphragms of a microscope?
There are two types of diaphragms of a microscope. There are disk and iris type diaphragms, the setting are dependent upon the transparency of the object, the degree of contrast desired and the objective lens selected.
What is optical bench model of microscope?
the principle of the microscope will be better understood by setting up such an instrument on the steel rule optical bench and using thin spectacle lenses in place of the more complicated objectives.
What did leeuwenhoek study?
Antonie van Leeuwenhoek was a scientist. He is most famous for his contributions to improving the microscope, and for setting the framework for the field of microbiology.
How much the onion cell magnified?
How much onion cells are magnified depends on what magnification setting a microscope is on. It is impossible to say how much they are magnified in a specific situation without more information.
What power must be in place when you first find an image in the microscope?
You should first use the lowest power setting of a microscope to find an object and then center it within the viewing area. Then, when you switch to the next higher magnification, your target should still be close to the center and easier to find and focus on.
What are some safety precautions you should take while handling with a microscope?
captured softly with strangeness and clean and clear the eye piece and adjust the setting of it very sincerely.
