Which type of microscope has the lowest magnification power?
The stereo microscope has the lowest magnification power among the different types of microscopes. It is typically used for viewing larger specimens at low magnification levels, usually ranging from 10x to 40x.
Why does an electron microscope have more resolving power than an optical microscope?
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 type of electron microscope?
One type of electron microscope is a transmission electron microscope (TEM). This microscope passes a beam of electrons through a thin specimen to create an image. Another type is a scanning electron microscope (SEM), which scans a focused beam of electrons across the surface of a specimen to create a detailed image.
What does the power of a microscope depend on?
Depends which type of microscope we are talking about. The common compund light microscope has a resolving power of 0.2 micrometer or 0.0002 millimeter. In comparison the human eye's resolving power is 0.1 millimeter. Resolving power is the minimum distance between two objects or particles such that the objects are distinguishable. So for example in the case of human eyes with resolving power of 0.1 millimeter, if you bring two objects any closer to each other than 0.1 mm, our eye cannot tell if they are two separate objects or not. Last but not least, the lower the resolving power, the higher the resolution. So because a compound microscope has a lower resolving power than human eye, it has a higher resolution.
Which type of microscope has the best resolution?
an electron microscope
What type of microscope would be best to view a peice of moldy bread?
A compound microscope.
What type of microscope would be best to view a drop of pond water?
compound light microscope
What type of microscope would be the best to view a piece of moldy bread?
we would use a light microscope
Which type of electron microscope is best for observing surface features and overall appearance?
The Scanning Electron Microscope
What type of microscope would be best to use to look at different cells or organelles?
scanning electron microscope
Which type of microscope would be best to use if you wanted?
To choose the best type of microscope, it depends on the specifics of your observation needs. For general biological applications, a light microscope is suitable for viewing cells and tissues. If you need higher resolution to see fine cellular structures, a transmission electron microscope (TEM) would be ideal. For three-dimensional imaging of surfaces, a scanning electron microscope (SEM) is preferred.
What does electronic microscope use instead of light?
It uses an electron beam. An electron microscope is a type of microscope that uses an electron beam to magnify and illuminate a specimen. An electron microscope has greater resolving power than a light microscope and can reveal the structure of smaller objects because electrons have wavelengths about 100,000 times shorter than visible light photons. They can achieve better than 50 pm resolution 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.
What type of microscope would be best to use if you wanted to look at the parts inside of a cell?
A transmission electron microscope (TEM) would be best for looking at the internal structures of a cell.TEM uses a beam of electrons to produce a detailed image of cell structures with high resolution around 0.1 nm.
Which type of microscope would be the best tool to use to view the surface of a bacterial cell And why?
A scanning electron microscope would be the best choice because the electron microscope can achieve a much greater resolution than that obtained with the light microscope because the wavelength of electrons is shorter than that of light.
What type of microscope would view the outside of a single cell the best?
A scanning electron microscope would provide the best view of the outside of a single cell because it can create detailed 3D images of the cell surface with high resolution. This type of microscope is ideal for observing the external features and structures of cells.
