They must be preserved and dehydrated. Once this is accomplished, put the specimen onto a slide, and then the slide is ready to be viewed under the microscope.

How must samples be prepared for observation by an electron microscope?
Samples for observation by an electron microscope are typically prepared by fixing the specimen in a chemical solution, dehydrating it, and then embedding it in a resin for stability. The sample is then sliced into ultrathin sections using a microtome before being stained to enhance contrast. Finally, the prepared sample is placed inside the electron microscope for imaging.

Can atoms be seen through an electron microscope?
Yes, atoms can be seen through an electron microscope. Electron microscopes use a beam of electrons rather than light to visualize samples at nanoscale resolutions, allowing for direct observation of individual atoms.
What type of microscope uses a beam of light?
A light microscope uses a beam of light to illuminate the specimen and magnify it for observation. This type of microscope is commonly used in biology and other fields for studying cells, tissues, and other biological samples.
Are samples for compound light microscope prepared on glass slides?
Yes
One limitation of the scanning electron microscope is that it cannot be used to?
One limitation of the scanning electron microscope is that it cannot be used to observe live samples or biological materials in their natural state. The high vacuum environment and the electron beam can damage or alter the sample.
What is the name of the strongest microscope?
The most powerful microscope is currently the electron microscope, specifically the transmission electron microscope (TEM) and scanning electron microscope (SEM). These microscopes use beams of electrons to achieve magnifications up to millions of times, allowing for incredibly detailed imaging of samples at the atomic level.
How much magnification does an electron microscope have?
An electron microscope can typically have magnifications ranging from 10,000x to over 1,000,000x. This allows for detailed imaging of samples at the nanometer scale.
in what way is a compound light microscope better than an electron microscope?
A compound light microscope is better for observing living organisms because it uses light to illuminate the sample, allowing for observation of dynamic processes. Electron microscopes, on the other hand, use electron beams and are better for observing smaller structures in high detail due to their higher resolution but cannot be used for living samples.
What microscopes can be used to view living samples I. compound microscope II. dissecting microscope III. scanning electron microscope IV. transmission electron microscope?
I and II. Compound and dissecting microscopes can be used to view living samples due to their lower magnification and non-destructive imaging techniques. III and IV. Scanning and transmission electron microscopes are not ideal for viewing living samples as they typically require a vacuum environment and can damage the specimens.

What is the name of a microscope that magnifies 200000 times?
A transmission electron microscope (TEM) is capable of magnifying up to 200,000 times. This type of microscope uses a beam of electrons to create high-resolution images of samples at the nanoscale level.
