The two main advantages of SEM over light microscopy is that the SEM has a much deeper depth of field and that it has higher resolution than a light microscope can achieve and the resultant much higher magnification from the SEM.
Scientists use electron microscopes, such as transmission electron microscopes (TEM) and scanning electron microscopes (SEM), to examine specimens that are smaller than what can be seen using a light microscope. These microscopes use beams of electrons instead of light to achieve higher resolution and magnification, allowing scientists to observe structures at the nanoscale.
Electron microscopes, such as transmission electron microscopes (TEM) and scanning electron microscopes (SEM), are commonly used to study viruses due to their high magnification and resolution capabilities. These types of microscopes allow scientists to visualize the detailed structure and morphology of viruses at the nanometer scale. Light microscopes may also be used to study larger viruses.
Electron microscopes, specifically transmission electron microscopes (TEM) and scanning electron microscopes (SEM), are capable of achieving magnifications up to 100,000 times. These microscopes use a beam of electrons instead of light to magnify the specimen, allowing for much higher magnification levels compared to light microscopes.
Transmission electron microscopes (TEM) and scanning electron microscopes (SEM) are capable of showing more detail compared to light microscopes. TEM utilizes electrons to pass through a specimen to create an image with high resolution and magnification. SEM scans a focused beam of electrons across a specimen's surface to produce a detailed 3D image.
Some disadvantages of microscopes include limited depth of field, potential distortion of the sample due to the lens, and the need for careful sample preparation and handling. Additionally, high-quality microscopes can be expensive and require maintenance and calibration.
Electron microscopes use beams of electrons to produce magnified images. There are two main types: transmission electron microscopes (TEM) and scanning electron microscopes (SEM). They are capable of achieving much higher magnifications and resolutions compared to light microscopes.

These microscopes use beams of electrons instead of light to achieve higher resolution and magnification, allowing scientists to observe structures at the nanoscale.
The scanning electron microscope (SEM) typically has the highest magnification among optical and electron microscopes, capable of magnifying up to 1,000,000x. This is considerably higher than the magnification achievable with light microscopes or transmission electron microscopes.
Electron microscopes use beams of electrons to illuminate objects. These microscopes offer higher resolution and magnification compared to light microscopes, making them suitable for detailed imaging of small structures. Transmission electron microscopes (TEM) and scanning electron microscopes (SEM) are common types of electron microscopes.
TEM (transmission electron microscope) and SEM (scanning electron microscope) use electron beams instead of light to magnify specimens, providing higher resolution images. Compound microscopes use visible light and lenses to magnify specimens. TEMs transmit electrons through the specimen to create an image, while SEMs scan the specimen's surface with electrons to generate an image.
Electron microscopes, particularly transmission electron microscopes (TEM) and scanning electron microscopes (SEM), can achieve magnifications of 1,000,000x or more. These microscopes use electron beams instead of light to create highly detailed images of samples at the nanoscale. This capability makes them invaluable for research in fields such as materials science, biology, and nanotechnology.

The advantages and disadvantages of the light microscope relate to light, magnification and resolution. Light microscopes magnify visible light--an obvious advantage, since this is what our eyes can see. Magnification (how large an object appears) and resolution (the clarity of details) are both limited when using light microscopes.
The magnification and resolution capabilities are highest in electron microscopes compared to light microscopes. Electron microscopes use a beam of electrons to achieve much higher resolution and magnification, allowing for the visualization of even smaller details in samples.
Two types of electron microscopes are the scanning electron microscope, or SEM, and transmission electron microscope, or TEM.
Electron microscopes, specifically transmission electron microscopes (TEM) and scanning electron microscopes (SEM), are capable of achieving magnifications up to 100,000 times. These microscopes use a beam of electrons instead of light to magnify the specimen, allowing for much higher magnification levels compared to light microscopes.
Scanning Electron Microscopes (SEM) use a focused beam of electrons to create high-resolution images of a sample's surface, while Transmission Electron Microscopes (TEM) pass electrons through a thin sample to create detailed images of its internal structure.
