An electron microscope is needed to examine a virus because viruses are extremely small, much smaller than the wavelengths of visible light. Electron microscopes use a beam of electrons to magnify the virus at a much higher resolution compared to light microscopes, revealing details of the virus's structure that would otherwise be impossible to see.
Because they are too small to be seen with a light microscope.

Which microscope should be ued for a virus is 50nm in size and why?
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?
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.
How can viruses be seen?
Viruses can be seen using an electron microscope, which has the magnification power to visualize these tiny infectious agents. Their small size, typically ranging from 20 to 400 nanometers, makes them invisible to the naked eye and even most light microscopes.
What type of microscope would you need to see detailed images of an internal structure of a bacterium a light microscope or an electron microscope?
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.
Are particles of carbon almost large enough to see with a 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.
What do you need to see a virus?
a powerful electron microscope
Would you use a stereomicroscope or compound light microscope or electron microscope to see a virus?
You would typically use an electron microscope to see a virus, as viruses are much smaller than what can be resolved using a compound light microscope or stereomicroscope. Electron microscopes use a beam of electrons to create high-resolution images of small objects like viruses.
What type of microscope would you use to view HIV?
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.

What microscope doesn't need light?
electron microscope
Electron microscope would be used if?
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.
When is it better to use a light microscope rather than an electron microscope?
When you need to observe a live specimen
What microscope would you need to see the details inside a bacterium?
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.
How can you see a chromosome?
You would need a scanning electron microscope (SEM)
Why cant individual chromosomes be seem with microscope?
You can not use a regular compound microscope, you need a scanning electron microscope (SEM) as they are too small.
What type of microscope do you need to see a ribosome?
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.
How can viruses be seen?
Viruses can be seen using an electron microscope, which has the magnification power to visualize these tiny infectious agents. Their small size, typically ranging from 20 to 400 nanometers, makes them invisible to the naked eye and even most light microscopes.
