Does a slide have to be wet in order to be examined for example if iam examining a specimen of potato starch powder does it have to be wet in order to be seen under the microscope?

Most slides have to be either wet or stained in order to be properly viewed under a microscope. This includes potatoes, where if you want to see the starch, you will have to wet the slide and add stain.

What is a microscope and how is it used?
A microscope is a scientific instrument with one or more lenses that enhances the view of smaller objects, for example, microorganisms (bacteria) and microsopic materials, which are too small to be seen with the naked eye. The eyepiece lens and objective lenses able to zoom in and out to enlarge and observe the specimens more clearly, with the objective lenses having a much better zoom-in ability. The eyepiece lens is at the top where you look into to observe the specimen. There are usually 3 or 4 objective lenses on a microscope held by a revolving nosepiece/turret, consisting of different times of zoom-in, e.g. 40x, 100x, 400x.... Also, there is a fine focus knob and a coarse focus knob. The coarse focus is for moving the objective lenses nearer/further away from the specimen while the fine focus is for fine-tuning the focus (usually when it is unclear). Use the coarse focus before the fine focus unless there is no need to zoom in on the specimen. Finally, an illuminator might shine a light on the specimen so that you can see it more easily.
What are the tools that scientists used to observe atoms?
They could use an electron microscope or an STM (scanning tunneling microscope)
What are differences between the light microscope and the electron microscope?
A light microscope uses a light source but a electron microscope has beams of electrons focused by magnetic lenses.The major difference in practice is resolution: the amount of detail that can be discerned in the image. Under optimal conditions (excellent lenses, oil immersion) the resolution of a light microscope is about 0.2 micrometers (or 0.000,000,2 meters or 2 thousandths of a millimeter). Objects that are closer together cannot be detected as separate. The resolution of an transmission electron microscope is about 0.05 nanometers (or 0.000,000,000,05 meters or half of 1 millionth of a millimeter). This means that the electron microscope has about 10,000 times the resolving power of the light instrument, and can therefore show far greater detail, for example of subcellular structure.Another difference of importance to biologists is that light microscopes (there are several kinds, such as bright field and phase contrast) enable the viewer to watch living cells. The electron microscope produces an image of the shadows cast by atoms of heavy metals used as stains; the living tissue is destroyed by the intense beam of electrons.

What is the difference in microscope and microscopic?
a microscope is an instrument for observing something up close; microscopic is something that is examined. For example, he examined a microscopic portion of the chemical.
What is the chemical that sometimes is used to make the specimen visible on a microscope?
An example is methylene blue.
Is what you look under a microscope is a specimen?
Yes - but a specimen can be something that is not observed under a microscope as well. For example, if you ever went on a walk in the country, picked a wildflower that grew there, and brought it home, you would have a specimen of a native plant that grew in the area where you found it.
Is what you look at under a microscope called a specimen?
Yes - but a specimen can be something that is not observed under a microscope as well. For example, if you ever went on a walk in the country, picked a wildflower that grew there, and brought it home, you would have a specimen of a native plant that grew in the area where you found it.
Chemical sometimes used to make the specimen visible on a microscope?
Methylene blue is an example.
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.
How can you use the word microscope in a sentence?
its easy like for example: Doctor Mikey examined the virus with a microscope but found no hope. or here is a simple sentence: Sam looked through the microscope but could not tell what it was she was looking at.
Can you give an example of a sentence using the word examining?
I am examining my cookie.
What is the different between light microscope and compound light microscope?
Answersimple first one is: their both different in quality. For example, a light microscope would use sunlight as its source of power,and therefore less effective. Compound microscope use electricity as its source of power for the same usage, which would be stronger and better to see the details in the specimen.
What is after the x on a microscope lens?
The amount the lens magnifies your vision by. For example "x20" means "times twenty" as in being able to see the object being examined 20 times larger.
What does specimen mean?
Subject or example Specimen can mean an example of something eg Submit a specimen of your hand writing to the court. or specimen can mean a small sample of something. eg The doctor asked for a urine specimen to be tested for infection.
