Really small things. Because there are limits to how small an object we can observe through a light microscope, we developed the electron microscope. By setting up a sample and streaming electrons at it to resolve an image, we can "see" things smaller than we'd be able to see through a light microscope.

This is wrong. Atoms are too small to be viewed in an electron microscope. Electron microscope can see things that are 2nm, but nothing smaller than that.
An electron microscope can either be used to see the surface of a cell (SEM=cCanning electron Microscope) or to see the structures inside a cell (Transmission Electron Microscope).
An electron microscope is the only kind of microscope that can be used to see all the structures inside a cell. You can see the smallest parts using fluorescens and staining the small ones, thus making them visible because they will be glowing while the rest of the cell is dark, but you can't actually see it. The plasma membrane can only be seen properly by using electron microscope.

Why are electron microscopes capable of revealing details much smaller that those seem through light microscope?
The resolving power of a microscope is a linear function of the wavelength - An optical microscope's wavelength is that of light, and the electron microscope's - that of vibrating electrons. As the electron microscope's wavelength is about 100,000 times smaller than that of light, we get a much better resolving power.
Do microscopes magnify unicellular organisms?
Yes. Microscopes magnify things. That is how they make it possible to see little bitty things.
What scientific tool would you use to look at something very small like bacteria?
BIOLOGISTS USE MICROSCOPE. FOR A DETAILED STUDY THEY USE ELECTRON MICROSCOPE. EVEN OTHER TECHNOLOGIST CAN USE MICROSCOPE. FINE TEXTURES COULD BE OBSERVED UNDER HIGH RESOLUTION MICROSCOPE.
What can microscopes do?
Microscopes magnify things so that you can visualize what you wouldn't be able to see with the naked eye. Microscopes are very helpful in scientific research to see cells etc...
What are the functions of a simple microscope?
Light microscope uses light to magnify a specimen. Human or plant cells, bacteria, and protists can be observed and analyzed using light microscopes. For much smaller things like virus or macromolecules, you will need much stronger microscopes, such as scanning electron microscopes.
Why dont scientists use electron microscopes on human subjects?
they use electron microscopes on human objects because they need it to look at things too small to be seen with a light compound microscope.
Can a scientist observe living things under an electron microscope?
Specimens are placed in a vacuum (high vacuum, requiring a cryopump to get to 10^-7 torr. Then the specimen is bombarded with an electron beam (like getting a shock). Not likely that something could survive that.
Name the two types of microscopes?
There are a variety of microscope types, but two large and different types are electron microscopes and optical microscopes. Optical microscopes are cheaper, and are commercially available for even you to buy. They work with lenses, and in many cases, oil emulsions. Electron microscopes work by bombarding specimens with electron beams. They are significantly more expensive than optical microscopes, but give a better quality image and come with vastly superior magnification levels, due to the fact that electrons have wavelengths circa 100,000 shorter than photons, or light. This enables you to see things in much greater detail.
What was the idea for a slinky mainly based on?
Thhe slinky was originally used as a spring to stablize things like platforms for electron microscopes.
What have modern microscopes made it possible to do?
The microscopes in our days make it easy to see the things that the naked eye can not. Light microscopes see objects down to about 500 nm. A nanometre = 1 metre/ 1000 000 000 Modern microscopes allow scientists to view individual cells but not see well the organelles in them. Electron microscopes are used to get details of organelles. An atom cannot be viewed through a microscope as it is about 1000 times less than the wavelength of visible light. An electron microscope can give the reflection of objects down to about a nanometre or slightly smaller. This is almost possible to view larger atoms.
A microscope used for viewing things through which light cannot pass is a?
a microscopes used for viewing things through which light cannot pass through is called a
What is one important advantage an optical microscope has over a more powerful electron microscope?
It is cheaper and used to observe larger objects. Electron microscopes look at much smaller things such as atoms.
Why did scientist take so long to conclude all living things are made of cells even with the help of a microscope?
Microscopes powerful enough to see cells weren't invented until the 1980s. These microscpes are called electron microscopes.
Why are electron microscopes capable of revealing details much smaller that those seem through light microscope?
The resolving power of a microscope is a linear function of the wavelength - An optical microscope's wavelength is that of light, and the electron microscope's - that of vibrating electrons.

What microscope can see a single cell?
A Light Microscope is capable of seeing a single cell. Electron Microscopes are designed to look at things far smaller than cells.
Do microscopes magnify unicellular organisms?
Yes. Microscopes magnify things. That is how they make it possible to see little bitty things.
What are the characteristics of scanning electron microscopes?
In an electron microscope, a stream of electrons takes the place of a beam of light and allows us to see things smaller even than light itself. A SEM produces images that appear 3-D.
