Short Answer:
Electron microscopes have much better resolution and are capable of much higher magnification than light microscopes because the wavelength of the electrons is thousands of times smaller than the wavelength of light.
Light microscopes can typically resolve structures to a fraction of a micron compared to electron microscopes which in practice achieve resolutions of a few nanometers. Practically, electron microscope can have almost a thousand times greater resolution than an optical microscope.
The useful magnification of an electron microscope is also in the range of a thousand times greater than an optical microscope.
The actual performance of any microscope depends on its design and lensing system and so significant variation exists in the above practical characteristics and performance of both types of microscopes can be enhanced in various ways.
Long Answer:
An electron microscope uses an electron beam to illuminate a specimen and produce the image.
An optical or light microscope uses a light beam to illuminate a specimen and produce the image.
A microscope of either type is characterized by its magnification and resolving power. The magnification depends on the lensing system and can be increased to any degree, but the maximum useful magnification is limited by the resolving power.
The resolving power of a microscope can not be better than the limits placed on it by the size of the wavelength of the illuminating beam. The smaller the wavelength, the smaller the structures that can be resolved in them image.
Visible wavelengths of light are a few hundred nanometers. An electron microscope operates with electrons accelerated to a few hundred thousand electron volts of energy and with a wavelength in the range of few hundredths of an Angstrom.
An electron microscope has a theoretical resolving power that is much greater than a light microscope and can reveal smaller structures because the electrons used have wavelengths (few hundredths of Angstroms) almost 100,000 times shorter than visible light (few hundred nanometers).
An optimized electron microscope can achieve a practical resolution of a few Angstroms and a useful magnifications in the millions of times.
A good light microscope can resolve structures smaller than a micron but is limited to about a few hundred nanometers resolution. The useful magnification of a light microscope is not much more than a thousand times.
The electron microscope uses electrostatic and electromagnetic fields to act as lenses to control and focus the electron beam and to form an image. An optical or light microscope employs glass lenses.

How do magnification and resolution compare between electron and light microscopes.?
Electron microscopes have higher magnification and resolution compared to light microscopes. Electron microscopes use electrons to create an image, allowing for much greater magnification and resolution due to the shorter wavelength of electrons compared to visible light used in light microscopes.
How do magnification and resolution compare between electron and light microscopes?
Electron microscopes have higher magnification and resolution compared to light microscopes. Electron microscopes use electrons instead of light to generate an image, allowing for much higher magnification due to the shorter wavelength of electrons compared to light. This results in electron microscopes being able to resolve smaller details in the sample compared to light microscopes.
How electron microscopes are different from light microscopes?
Electron microscope gives a greater magnification. Instead of lenses, the electron microscope uses magnets to aim a beam of electrons at thin slices of cells. A light microscope does not have as good as a magnification and resolution as a electron mircroscope does. A microscope as a curved lens, so the light bounces off of it and makes the small object larger.
Which comparator has highest magnification?
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.
What are the advantages of electron microscopes?
Electron microscopes provide high resolution images, allowing for visualization of small details at the nanometer scale. They have a greater magnification power compared to light microscopes, making them suitable for studying ultrafine structures. Electron microscopes can also provide information on the composition of materials through energy-dispersive X-ray spectroscopy.
