Magnification and resolution is in light microscope is about 500x and 0.2micro metres respectively than human eye.In e.microscope magnification is about 200,000x and resolution is 0.0005micro metres. You cannot observe live specimen through electron microscope. Lenses in light microscope are glass while e.microscope use magnetic lenses. E.microscope is relatively very larger than light microscope. You need special knowledge to handle electron microscope. You can observe through naked eye in e.microscope. A beam of electrons is sent through specimen in e.microscope.In light microscope a beam of light is sent. Electron microscope is very complex relative to light microscope.
A light microscope uses a light source but a electron microscope has beams of electrons focused by magnetic lenses.The major difference in practice is resolution: the amount of detail that can be discerned in the image. Under optimal conditions (excellent lenses, oil immersion) the resolution of a light microscope is about 0.2 micrometers (or 0.000,000,2 meters or 2 thousandths of a millimeter). Objects that are closer together cannot be detected as separate. The resolution of an transmission electron microscope is about 0.05 nanometers (or 0.000,000,000,05 meters or half of 1 millionth of a millimeter). This means that the electron microscope has about 10,000 times the resolving power of the light instrument, and can therefore show far greater detail, for example of subcellular structure.Another difference of importance to biologists is that light microscopes (there are several kinds, such as bright field and phase contrast) enable the viewer to watch living cells. The electron microscope produces an image of the shadows cast by atoms of heavy metals used as stains; the living tissue is destroyed by the intense beam of electrons.
microscopes are much more powerful

An artesian well bubbles up out of the ground all by itself.
A compound microscope, like the common optical microscope is used to study objects too small to see with the naked eye. The difference between a common optical microscope, and a compound microscope is the number of objective lenses. A compound microscope will contain several lenses. This reduces distortion, and gives one multiple lenses with which to adjust magnification.
A transmission electron microscope uses a beam of electrons to create detailed images of the internal structure of a sample, while a scanning electron microscope uses a focused beam of electrons to create high-resolution surface images of a sample.
Electron microscopes can see much closer than a light microscope, and they use electrons to paint a picture of what the object looks like. Giving a very detailed and small picture that can be viewed on a monitor.
A light microscope uses visible light to magnify and view specimens, offering lower magnification and resolution compared to a scanning electron microscope (SEM) which uses a focused beam of electrons to image the sample, providing higher magnification and resolution. SEM can produce 3D images of the sample surface while light microscopes typically provide 2D images.
A light microscope uses visible light to illuminate a sample and magnify its image, making it suitable for observing living cells and larger biological structures. In contrast, an electron microscope uses a beam of electrons to create a highly detailed image of the sample at a much higher magnification, enabling the visualization of smaller structures such as viruses and proteins.
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.
EXTRA!!
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.
Optical microscopes use visible light to magnify objects, providing lower resolution images compared to electron microscopes which use beams of electrons to achieve higher magnification and resolution. Electron microscopes are able to see smaller objects in more detail due to the shorter wavelength of electrons compared to visible light.
The compound microscope is a light microscope that uses light to "see" microbes. Viruses are too small.The electron microscope uses electrons to "see" microbes or viruses.

The difference between a tied grant and an ordinary grant is that a tied grant has conditions and the ordinary grants don't!
Yes, most bacteria are too small to be seen with an ordinary light microscope. Bacteria are generally between 0.5 to 5 micrometers in size, which is below the resolution limit of a light microscope which is about 200 nanometers.
