What is the difference between a Light Microscopes and an Electron Microscope?
The optical microscope is the most common. It uses light to image a sample that is too small to be seen by the naked eye.The scanning electron microscope examines the surface of objects using an electron beam and measuring reflection.Short Answer = Resolution.
What is the difference between compound microscope and an electron microscope?
A compound microscope is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy. Microscopic means invisible to the eye unless aided by a microscope. An electron microscope is a type of microscope that uses a beam of electrons to illuminate the specimen and produce a magnified image. Electron microscopes (EM) have a greater resolving power than a light-powered optical microscope, because electrons have wavelengths about 100,000 times shorter than visible light (photons), and can achieve better than 50 pm resolution[1] and magnifications of up to about 10,000,000x, whereas ordinary, non-confocal light microscopes are limited by diffraction to about 200 nm resolution and useful magnifications below 2000x.
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.
What instrument is used to see a magnified view of a very small objects?
A microscope
When was the electron microscope invented?
1928 i believe by the Germans... someone check me on that... it wasnt the electron microscope we know today but it was the same concept only it magnified by a small 17 times... it has be improved since then
Objects that are too small to be seen with other microscopes can be observed with a what kind of microscope?
electron microscope
Which type of microscope can be used to observe very small subcellular structures?
Transmission electron microscope.
What are the uses of an electron microscope?
viewing objects too small to be seen with visible light.
Small internal cell structure best observe in microscope?
C) transmission electron
How do light microscopes defer from electron microscopes?
electron microscopes can help you see very small small organisms. Unlike a light microscope A light microscope uses visible light, focussed by lenses. An electron microscope uses beams of electrons, focussed by magnetic coils. The electron microscope can indeed image smaller objects than an optical (light) microscope. Both can image objects smaller than can be seen with a magnifying glass.
What is the best microscope to use when viewing small objects?
Electron microscope which is ten thousand times better than a normal one
Which microscope has better resolution?
The electron microscope because Electron microscopes can obtain pictures of extremely small objects-- much smaller than those that can be seen with light microscopes.

Microscope that can enlarge images up to 1500 times?
A microscope is an optical device which is used to view very small objects. A compound microscope enlarges images up to 1,500 times.
What type of microscope is best for studying DNA?
electron microscopes...According to my course in OK Virtual Highschool.."Hi-tech electron microscopes are used to study very small objects such as viruses. They can also be used to view the smallest of molecules that make up cells such as DNA in the nucleus. Unlike a compound microscope, an electron microscope can produce a three-dimensional image"
What do things that are to small for a light microscope get viewed by?
An electron microscope.
What is the microscope?
A microscope is an object that enlarges small objects.
