viruses
An electron microscope is best suited for studying objects at the nanometer scale, such as viruses, bacteria, cell structures, and nanomaterials. It provides high-resolution images and can reveal details that are not visible with a light microscope.
It is not possible to see organelles with a compound light microscope because some organelles are to small to be seen with the low magnification of the light microscope. If they can not be seen through the compound microscope they are normally looked at through the electron microscopes (transmission electron microscope {TEM} or scanning electron microscope {SEM}).
electron microscopes...According to my course in OK Virtual Highschool.."Hi-tech electron microscopes are used to study very small objects such as viruses. They can also be used to view the smallest of molecules that make up cells such as DNA in the nucleus. Unlike a compound microscope, an electron microscope can produce a three-dimensional image"
A transmission electron microscope (TEM) would be best for looking at the internal structures of a cell.TEM uses a beam of electrons to produce a detailed image of cell structures with high resolution around 0.1 nm.
Light microscope, also known as an optical microscope, can be used to study cells. Electron microscopes, including transmission electron microscopes (TEM) and scanning electron microscopes (SEM), are also commonly used to study cells at higher magnifications. Fluorescence microscopes are utilized to visualize specific structures within cells using fluorescent markers.
Actual magnification of light microscopes could reach up 1000x magnification depending on the type of light microscope. Light microscopes could be divided into brightfield microscope and phase-contrast microscope for viewing stained specimen and unstained specimen respectively. Magnification of electron microscope on the other hand could go up to 1000000x. The actual magnification as well depends on types of electron microscope which includes transmission-electron microscope and scanning-electron microscope where both of them are used in viewing internal cell structures and cell surface structures respectively.
Its an electron microscope.It might be scanning electron microscope or TEM
Because if the microscope wasn't invented we would have no clue that cells existed.
scanning electron microscope
No, it was so incredibly small that he couldn't see it until the electron microscope ws invented in 1933.

They could use an electron microscope or an STM (scanning tunneling microscope)
You're probably thinking of the scanning electron microscope. But it could be anything. Your question is not specific enough.
An electron microscope is best suited for studying objects at the nanometer scale, such as viruses, bacteria, cell structures, and nanomaterials. It provides high-resolution images and can reveal details that are not visible with a light microscope.
An electron microscope is a non-optical microscope that can magnify up to 250,000 times or more. By using a beam of accelerated electrons instead of light, electron microscopes provide extremely high resolution images of samples at the atomic and molecular level.
A virus of 50nm would be too small to see unless an electron microscope was used because it has greater resolving power and a resolution up to .1nm. A microscope using compound light as the means of illumination could not resolve better than approx. 200nms.
