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.

What is a microscope in science?
There is a compound light microscope, an scannignn electron microscope, and transmission electron microscope.
What types of microscopes?
The four main types of microscopes are the Light Microscope, Electron Microscope, the Transition electron microscope and Scanning electron microscope.
What is the difference between ordinary microscope and electron microscope?
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.
What are the two different types of microscopes?
Light microscope Electron microscope
How many types of microscope are there?
There are many. Simple microscope, compound microscope, light microscope, scanning electron microscope, Transmission Electron Microscope, Dissection microscope, etc,but all together there are about 20 different types of microscopes.
What is the differences between a compound and electron microscope?
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.
Microscope that uses differences in light intensity?
Electron Microscope. Not sure though
What are the key differences in imaging capabilities between a transmission electron microscope and a light microscope?
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.
What came first electron microscope or light microscope?
compound light microscope - cell theory - electron microscope
How does an electron microscope differs from a light microscope?
The light microscope use the visible light; the electron microscope use an electrons beam.
What is a microscope in science?
There is a compound light microscope, an scannignn electron microscope, and transmission electron microscope.
Is a electron microscope a light microscope?
yes
What types of microscopes?
The four main types of microscopes are the Light Microscope, Electron Microscope, the Transition electron microscope and Scanning electron microscope.
Explain the difference between a light scanning and electron microscope?
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.
Which microscope do not use a beam of light?
An electron microscope does not use a beam of light. Instead, it uses a beam of electrons to visualize specimens at much higher resolution than can be achieved with light microscopes.
What are the differences between a light microscope and a transmission electron microscope in terms of their imaging capabilities and applications?
A light microscope uses visible light to magnify and view samples, providing lower resolution images suitable for observing living cells and tissues. In contrast, a transmission electron microscope uses a beam of electrons to achieve higher resolution images, making it ideal for studying ultra-thin samples and structures at the molecular level.
What microscope doesn't need light?
electron microscope
