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.

A Tunneling Electron Microscope will be required.
You need Electron microscopes in order to examine or view a virus because you can't see it from ordinary microscopes
An electron microscope
electron microscope
Approximately 130 nanometers for average. Size varies by specific virus, however, and influenza viruses can range from 10 to 300 nanometers. The nanometer is equal to one billionth of a meter, or one millionth of a millimeter. They are about 1/100th the size of bacteria. Most are "nano" size and too miniscule to be seen with a regular light microscope, so electron microscopes need to be used to visualize the virus particles.
They vary significantly depending on the type of virus, however, viruses are sub-microscopic and require an electron microscope to visualize and very very tiny compared to the size of bacteria. For example: The swine flu viruses (including Novel H1N1 2009 Swine Flu) are very similar in structure to all Influenza Type A viruses. They are also very similar in size to most viruses. They are about 1/100th the size of bacteria. Most are "nano" size and too miniscule to be seen with a regular light microscope, so electron microscopes need to be used to visualize the virus particles. When measured they have a diameter of 10 to 300 nanometers. The nanometer is equal to one billionth of a meter, or one millionth of a millimeter.
ribosomes are not seen by using a light microscope bcz of its small size
Viruses are MUCH smaller than cells in size.
No, the actual size never changes - only the APPARENT size, due to the magnification provided by the lenses of the microscope.
The electron microscope.
Transmission elctron microscope
Viruses can only be seen with electron microscopes
Everyhting you see in the microscope and especcialy what you are supposed to see. You should make a note of what you are looking at and which magnitute you are using to give the viewer sence of the actual size of the object.
a wave that is about the size of a virus is ultraviolet a wave.

The lower power objective for the microscope is the small lense on the microscope. The size usuall ranges at 4x on the microscope.
a microscope measures the size of an object (example: how big an blood cell is)
it is 2 grams
o.ooo1 (Influenza Virus)
A virus is much much much smaller then a bacterium. Virus called phage can infect bacteria.
