because viruses are very small and can not seen by any light microscope.only electron microscopes that use electron radiation that have wavelenght about .005 nanometer have enough resolving power to detect such a small particles as viruses
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.
Electron microscope would be used if higher magnification and resolution are required to visualize objects at the nanometer scale. It is suitable for studying the ultrastructure of cells, tissues, and materials with high detail and clarity.
An electron microscope would be needed to see detailed images of an internal structure of a bacterium, as it can provide much higher magnification and resolution compared to a light microscope. The electron microscope uses a beam of electrons instead of light to visualize the specimen, allowing for better visualization of internal structures at the cellular level.
Viruses are incredibly small - much smaller than the smallest of bacteria, even though many millions of bacteria could fit on a pinhead. Therefore viruses can only be seen with the help of a very powerful microscope such as a scanning ellectron microscope.
No, individual carbon particles are much smaller than the resolution limit of a light microscope, which is around 200 nanometers. A scanning electron microscope or a transmission electron microscope would be needed to visualize individual carbon particles, which are typically on the nanoscale.

You would need an electron microscope to view HIV because it is a virus and is too small to be observed with a light microscope. Electron microscopes use a beam of electrons to create high-resolution images of tiny objects like viruses.

When you need to observe a live specimen
You would typically need an electron microscope to see the details inside a bacterium, as the resolution of an electron microscope is much higher than that of a light microscope. Electron microscopes use a beam of electrons to create an image, allowing for detailed visualization of the internal structures of bacteria.
You would need a scanning electron microscope (SEM)
You can not use a regular compound microscope, you need a scanning electron microscope (SEM) as they are too small.
You would need an electron microscope to see a ribosome, as they are very small structures, typically around 20-30 nanometers in size, which are below the resolution limit of a light microscope. Electron microscopes use a beam of electrons instead of light to achieve much higher resolution.
