Microscopes
Microscopes are used to look at things that are not visible to the naked eye. This category would demonstrate how microscopes work and information about different kinds of microscope.

What is the purpose of scanning?
To scan a document into electronic format is to have it electronically available. The you can email the copy, upload it online or change it as you wish. Also having documents in electronic format means you can get rid of the originals which may be many filing cabinets.
How can microscopes help us do an experiment?
Microscope will help us to view/see even very minute details of anything being experimented.
Function of limb lamb in microscope?
A limb clamp in a microscope is used to secure and hold the slide in place during observation. It helps prevent movement or shaking of the slide, which can affect the clarity and accuracy of the image being viewed under the microscope. The limb clamp is an essential part of the microscope for ensuring a stable and steady platform for examining specimens.
What is the major difference between the light microscope and the electron microscope?
Electron microscopes can see much closer than a light microscope, and they use electrons to paint a picture of what the object looks like.
Giving a very detailed and small picture that can be viewed on a monitor.
The child's microscope may have the same magnification, but does not have the same type of lens or fine tuning available on better microscopes. The image may be somewhat distorted.
How do microscopes help scientists do research?
Microscopes allow scientists to confirm what is happening on a small scale. For example, we can observe the effects of a new drug on liver cells. It merely makes it easier to empirically check theories.
When you look at soil under a microscope what is between the particles?
When looking at soil under a microscope, you will find spaces between the particles filled with air and water. These spaces are important for allowing roots to grow, allowing air and water to move through the soil, and providing habitat for microorganisms.
Does TalkTalk allow port scanning?
im not sure about port scanning but we do talktalk they are terrible the charged us £200 out of no where and there excuse was they change somthing slightly even though we checked with their company a week before so now we cant use the phone.
soz i wasnt sure about the answer
On what microscope platform is a slide placed for viewing?
The microscope stage is the platform on which a slide is placed for viewing.
Proper way to carry a microscope?
you hold the neck with one hand and the base with the other hand. you should never hold the arms or else it will break.
How many lenses do simple microscopes use?
Just One A Convex one a simple microscope is a simple magnifier?
What does the coarse adjustment do on a microscope?
The coarse focus adjustment moves the lens (or the stage, depending on the construction of the microscope). So does the fine adjustment but the fine does it much less and much more accurately (less play in the gears)
List the four assessments of the quality of the image being seen using a light microscope?
[1] Brightness - How light or dark is the image? Brightness is related to the illumination system and can be changed by changing the voltage to the lamp (rheostat) and adjusting the condenser and diaphragm/pinhole apertures. Brightness is also related to the numerical aperture of the objective lens (the larger the numerical aperture, the brighter the image).
[2] Focus - Is the image blurry or well-defined? Focus is related to focal length and can be controlled with the focus knobs. The thickness of the cover glass on the specimen slide can also affect your ability to focus the image -- it can be too thick for the objective lens. The correct cover-glass thickness is written on the side of the objective lens.
[3] Resolution - How close can two points in the image be before they are no longer seen as two separate points? Resolution is related to the numerical aperture of the objective lens (the higher the numerical aperture, the better the resolution) and the wavelength of light passing through the lens (the shorter the wavelength, the better the resolution).
[4] Contrast - What is the difference in lighting between adjacent areas of the specimen? Contrast is related to the illumination system and can be adjusted by changing the intensity of the light and the diaphragm/pinhole aperture. Also, chemical stains applied to the specimen can enhance contrast.

Enumerate the proper ways of handling and caring the microscope?
hold it with both hands soit does notdrop or accidentally hit something.
it is the COURSE adjustment knob

What effects did the microscope have on science and society at that time and present day?
at that time, it aided in the discovery of cells as the building block higher organisms and the germ theory of disease
now many various forms of microscopy is used in chemsitry, biology, medicine and all their sub-disciplains
