What else can I help you with?
Is electron microscopes good for watching cells growing?
No.They are not but they are good for observing 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.
Who discovered electron microscopes?
The electron microscope was invented by Max Knoll and Ernst Ruska in Germany in 1931. Ruska was awarded the Nobel Prize in Physics in 1986 for his contribution to the development of electron microscopy.
What are the lenses in electron microscopes made from?
The lenses in electron microscopes are typically made from electromagnets, rather than glass lenses used in light microscopes. These electromagnets focus and direct the electron beam to generate high-resolution images by controlling the path of the electrons.
When would you use a light microscope instead of an electron microscope?
light microscope make it possible to study dead organisms and their parts, and to observe some tiny organisms and cells while they are still alive. TEMs a type of electron microscope can reveal a wealth of detail inside the cell.SEMs another type of electron microscope produce realistic, and often dramatic,three-dimensional images of the surfaces of objects. however electron microscopes only work with preserved dead and dehydrated specimens.

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 do electrons microscopes use to focus and magnify an image?
Electromagnets focus the electron beam on the specimen. This is a good advantage of electron microscopes over traditional light microscopes where lenses have to be used. Electromagnets can be used as electrons are charged particles and are deflected by magnetic fields.
Are light microscopes more powerful than electron microscopes?

How might disease scanning electron microscopes help diagnose and treat?
idk, im trying to find out the same question. your guess is as good as mine
Which microsope shows atoms on the surface of a molcule?
Transmission Electron Aberration-Corrected Microscope (TEAM) is the only one capable of resolving individual atoms. Scanning Electron Microscopes can resolve a good amount of macromolecules.
Are viruses seen under an electron microscope?
Only the largest of viruses (e.g. Pox viruses) can be seen with a good light microscope (albeit with poor detail). Viruses usually can only be seen by electron microscopy. [2nd year Dental student, Naser]

Do electron microscopes have greater magnification than light microscopes?
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.
What is a good company to purchase used microscopes from?
There are many good companies that one can chose to purchase quality used microscopes. This includes companies such as Metallography and Gradient Lens.
