To see a virus, a Transmission Electron Microscope (TEM) or a Scanning Electron Microscope (SEM) would be better than a compound light microscope. TEM uses a beam of electrons to create an image with high resolution and can visualize viral structures inside cells. SEM provides detailed 3D images of virus surface morphology at a higher magnification than a compound light microscope.
A light microscope is commonly used to view cardiac muscle tissue. Electron microscopes can also be used for more detailed imaging of the ultrastructure of cardiac muscle cells.
A transmission electron microscope, known as TEM, refers to a form of electron microscope wherein an image is derived from electrons that have passed through the specimen. It is used to study objects at the atomic level.
Cell biologists use a transmission electron microscope (TEM) to study the internal structures of cells. This powerful microscope allows them to visualize organelles, membranes, and other subcellular structures at very high resolution. TEM is especially useful for studying cellular ultrastructure and identifying organelles in detail.
Transmission electron microscopes (TEM) generally have greater magnification than scanning electron microscopes (SEM). TEM can achieve magnifications up to 1,000,000x, while SEM typically reaches up to 100,000x.
light microscope or SEM or TEM electron microscopy
A scanning electron microscope (SEM) uses a focused beam of electrons to create detailed surface images of a sample, while a transmission electron microscope (TEM) transmits electrons through a thin sample to create detailed internal images. SEM is used for surface analysis, while TEM is used for studying internal structures at a nanoscale level.
A transmission electron microscope (TEM) uses electrons instead of light to image samples. Electrons have a much smaller wavelength than visible light, allowing for higher resolution images with finer details in a TEM compared to a light microscope. Additionally, TEMs can magnify images up to a million times, providing a higher level of detail in the sample.

A scanning electron microscope (SEM) uses a focused beam of electrons to create detailed surface images of a sample, while a transmission electron microscope (TEM) transmits electrons through a thin sample to create detailed internal images. SEM is used for surface analysis, while TEM is used for studying internal structures at a higher resolution.

An electron microscope is a microscope that uses beams of electrons instead of rays of visible light to form highly magnified images of tiny areas materials or biological specimens. Comparing light vs electron microscopes is made more complicated by the fact that there are different types of electron microscopes.
The key differences in imaging capabilities between a transmission electron microscope (TEM) and a light microscope are the resolution and magnification. TEMs use electron beams to achieve much higher resolution and magnification than light microscopes, allowing for the visualization of smaller details in samples. Additionally, TEMs can image internal structures of cells and tissues in greater detail due to their ability to penetrate through thicker samples compared to light microscopes.
transmission electron microscope
The transmission electron microscope operates on the same principle as the light microscope but uses electrons instead of light. What you can see with a light microscope is limited by the wavelength of light. Transmission electron microscopes use electrons as "light source" and their much lower wavelength makes it possible to get a resolution a thousand times better than with light microscope.

There are several type of microscopes, mainly, the one that we use in lab is a simple light microscope or a compound microscope. Then we have the phase contrast microscope, fluorescent microscope, electron microscope (transmission electron microscope [TEM] and scanning electron microscope [SEM]), confocal microscope and even dissection microscope the one which we use during dissections.
