depending on what microscope, a beam of light or electron bean has to be able to permeate parts of the sample

Why must you use a thin specimen when viewing with a light microscope?
For a light transmission microscope, a thin sample is needed in order for the light to pass through the sample from the light source on the other side. However, you can use a dissection microscope (another type of light microscope) which illuminates the sample from above, eliminating the need for a thin sample size. As the name suggests, this is normally used in dissections, and is of low magnification.
What is a microscope that creates image of the surface of a sample?
microbiology
How do you examine water for living things?
Normally, a sample of water is put on a microscope slide and examined using the microscope.
How do you use a microscope to view cells?
Use the fine adjustment on ur microscope its the small knob
What do the stage on the microscope do?
It holds the sample in the stage clips at the focal point.
Using a powerful microscope it is possible to see hydronium and hydroxide ions in a sample of pure water?
no
To observe a small living organism a scientist might use a?
Microscope. A scientist might use a microscope. Well actually, it depends on the size of the animal. If it is microscopic, then scientists might have to observe it using it using a microscope. If it can actually be seen, then scientists mught actually take a sample of it back to the labratory to observe physically.

What is a microscope slide and what is it used for?
A microscope slide is a small rectangular piece of glass that the sample (the thing you're looking at) is placed on for observation. Generally, the sample is next covered with a cover strip (a small piece of plastic, used to keep the sample from sliding). The slide makes it possible to look at the sample. Otherwise, the sample would fall into the microscope light, which would be a little inconvenient.
What is the principle of microscope?
There are two types of the electron microscope. First is called transmission electron microscope. It uses electrons passed through the sample to build a picture of the sample internal structure. Second type is scattered ("reflected" from the sample surface) electrons to build up a picture of the sample surface.
Compare the sources of the beam in light microscope and electron microscopes?
Sample illumination is achieved in different ways in a light and electron microscope.In a light microscope, the sample is illuminates with light (photon energy)In an electron microscope, the sample is illuminated by a beam of electrons.Devon

Sample of optical instrument?
Example of an optical instrument? (not sample) Microscope.
Why are the stains on an electron microscope lead or gold?
You can look at any type of sample under an electron microscope. Depending on the sample, it can handle a certain amount of electrons on the surface (from the microscope). After this limit is reached, no image from the microscope can be obtained. This is because electrons can no longer "stick" to the sample and they start flying around crazily. Coating the sample with another substance, such as gold or lead, will allow the sample to handle a greater amount of electrons. The larger the amount of electrons on the surface, the finer the details one can obtain from their sample.
