The electron microscope is used to view things such as viruses as they are to small to be seen on a light microscope
An electron microscope is typically used to see details of a 300 nm virus as it provides higher resolution images compared to light microscopes. Transmission electron microscopes (TEM) and scanning electron microscopes (SEM) are common types used for this level of magnification.
A virus is much smaller than the resolution limit of a light microscope, which is about 200 nanometers. Viruses typically range from 20-400 nanometers in size, making them too small to be seen with a light microscope. Detection usually requires an electron microscope, which has much higher magnification capabilities.
A comparison microscope is commonly used to see fingerprints. This type of microscope allows two objects (such as two fingerprint samples) to be viewed side by side, making it easier to analyze their similarities and differences.
A compound light microscope is commonly used to see the cross section of a stem. This microscope uses multiple lenses to view thin slices of specimens that have been mounted on slides. It is particularly useful for observing the internal structures of biological samples.
A good sentence with the word 'microscope' in it might be; I studied the strangely active bacteria under my microscope.
Swine flu is caused by a virus. Viruses are submicroscopic organisms that are so small they can only be "seen" with an electron microscope. A regular microscope does not allow us to see things as small as a virus particle. See the related questions below for additional information about the pathogen that causes the H1N1/09 swine flu.
No. The flu (influenza) is caused by a virus. See related questions below.
You can't with the naked eye because they are submicroscopic particles, but with electron microscopes they can be seen. See the related link below for a picture of the virus taken through an electron microscope.
Electron microscope
Using an electron microscope will help you see a virus.
An electron microscope is necessary to actually see a virus.
An electron microscope can be used to see a virus. MRI's now exist that can see inside viruses. If you visit Florida State University, they have one.

a powerful electron microscope
Since a virus is far smaller than a typical cell (much smaller than a prokaryote) a virus cannot be seen by a regular microscope. To see a virus, you should get an electron microscope.
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.
Yes, the flu is a very easily spread virus. See the related questions about prevention.
