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 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.
How does an electron microscope resolution compare with a light microscope?
It's much, much higher. Optical microscopes are limited - by the magnification of the lenses. Electron microscopes don't have that restriction.
What is the maximum power of magnification of a microscope?
Actual magnification of light microscopes could reach up 1000x magnification depending on the type of light microscope. Light microscopes could be divided into brightfield microscope and phase-contrast microscope for viewing stained specimen and unstained specimen respectively. Magnification of electron microscope on the other hand could go up to 1000000x. The actual magnification as well depends on types of electron microscope which includes transmission-electron microscope and scanning-electron microscope where both of them are used in viewing internal cell structures and cell surface structures respectively.
What is the main difference between compound light microscopes and electron microscopes?
light microscopes direct light onto the slide and magnify it, light microscopes also have a high and low power objective lens which can magnify up to 10, 40, 43 and 100 times total magnification whilst electron microscopes shoot electrons at the slide which give more detail and accuracy but the disadvantage is it can't view objects in color. electron microscopes can magnify up to 500.000 times total magnification.Light microscopes aren't as strong as an electron microscope in respect to zooming power. The specimen can remain alive in light microscope but for electron microscopes, preparation of the slides will kill the specimen.
How are light microscopes and electron microscopes are different?
Light microscopes use light zo you can see close up but they are not as powerful. Electron microscopes use of coarse electrons and thats when you see the really close up of cells.
Are light microscopes more powerful than electron microscopes?
Yes, electron microscopes have a much higher possible magnification than compound light microscopes. An electron microscope is capable of 10,000,000 times magnification, whereas a good compound light microscope is capable of 1,000 - 2,000 times magnification.
One advantage of electron microscopes over light microscopes is their?
Higher Magnification

Do light microscopes allow us to observe specimens in greater detail than electron microscopes?
No
What is the difference in the way light microscropes and electron microscopes produce images?
There compared by frist the electron micrscope the electron microscope you can cut into a cell (any) and there huge they can zoom into about 2000X.The light microscope has a light to see [other one doesn't need] and light one can only zoom to 20X.
What types of objects can be studied with a light microscopes. what types can be studied with an electron microscopes?
Light microscopes are used to study living organism and to watch and analyze their structures. Electron microscopes use a dead specimen and are able to observe structures in great detail and with much much higher magnification. +++The electron microscope has a far higher definition and magnification than an optical microscope could achieve, but as you say you could not use it to study a living organism.
What is an advantage of light microscopes compared to electron microscopes is that light microscopes?
Light microscopes allow you to view living specimens and electron microscopes do not allow this.
