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.
Things that are too small for a light microscope, such as viruses and molecules, can be viewed using an electron microscope. Electron microscopes use a beam of electrons instead of light to magnify objects at a much higher resolution than light microscopes.
You would use a microscope to look at something very small like bacteria. There are different types of microscopes, such as light microscopes and electron microscopes, that can magnify objects at the microscopic level.
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.
Not really. An electron microscope requires that the specimen be placed in a vacuum for viewing. It would most certainly kill any living creature placed inside it. No, the specimen being viewed is incapible of life after being placed into the slit.
Yes, microscopes can magnify unicellular organisms to make them visible to the human eye. By using lenses to magnify the image, microscopes can make details of these tiny organisms clearer and easier to study.
No, electron microscopes cannot visualize living things because the high-energy electron beams used in these microscopes can damage or destroy biological samples.
Microscopes that can see small things include light microscopes, electron microscopes, and scanning probe microscopes. Light microscopes use visible light and lenses to magnify objects, electron microscopes use beams of electrons to achieve higher magnification and resolution, and scanning probe microscopes use a physical probe to scan the surface of the sample.
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.

No, electron microscopes require specimens to be in a vacuum chamber, which is not compatible with living organisms that need to be in a natural environment to survive. Instead, scientists typically use light microscopes to observe living organisms.
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.

Things that are very small, such as viruses, bacteria, and the detailed structure of cells, are only visible with an electron microscope due to their size being beyond the resolution of light microscopes.

Yes, electron microscopes have the ability to create detailed images of the internal structure of objects at a nanoscale level. By using a beam of electrons instead of light, electron microscopes can reveal features that are not visible with traditional light microscopes.
Microscopes have improved over time through advancements in optics, such as the development of compound microscopes with multiple lenses for higher magnification. Additionally, the invention of electron microscopes has enabled scientists to visualize objects at a much smaller scale than is possible with traditional light microscopes. Continual improvements in technology have also led to the development of techniques like confocal microscopy and super-resolution microscopy, allowing for even greater detail and resolution in imaging.
Microscope is the instrument used in studying cells, allowing scientists to view cells in detail and observe their structure and function. Different types of microscopes, such as light microscopes and electron microscopes, are used depending on the level of detail needed for the study.
