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?
anyone walking into a room with one in it can discover one. electron microscopes were invented by Ernst Ruska & Max Knoll.
What are the lenses in electron microscopes made from?
The lenses used in transmission electron microscopes aren't made of glass at all. Rather, they're made through electromagnetic energy, which helps focus the electrons being passed through.
How are electron microscopes different from light microscopes?
An electron microscope can produce greater magnification, and thereby make smaller objects visible, than a light microscope can.Short Answer: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.

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.
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.
What was leeuwenhoeks contribution to the discovery of cells?
Leeuwenhoek was very good at improving microscopes through good lens grinding. He built as many as 500 microscopes in his lifetime. "He was able to study the structure of tissue, and was one of the first scientists to discover protozoa in water,"according to Bizarre Labs.com.
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]
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.
Why do microscopes need stage clips?
Microscopes need stage clips in order to hold the slide or specimen in place. However, they are adjustable or removable on some microscopes, which is good, since you don't always need them.
