One advantage of electron microscopes over light microscopes is their _____.
A. size
B. higher magnification
C. two-dimensional image
D. use of live specimens
An electron microscope has no size advantage, it is usually much larger than any other microscopes. Most recent microscopes give a 3D view of the specimen and electron scopes can create complex 3D images that can sometimes be viewed 360o. Generally, the only scope that is used on live specimens is a dissection scope because of its lower magnification and lack of needing any slides or slide covers, in an electron scope the specimen must be dead or origionally inanimate. The only advantage a electron scope has over the others is its higher magnification (B). As far as I know it is the highest magnification scope manufactured in modern times.
The correct answer is B. higher magnification.
Electron microscopes have a higher magnification compared to light microscopes, which allows them to produce much more detailed images. To understand why this is the case, it's important to know the basic principles of how these microscopes work.
Light microscopes use visible light to illuminate a specimen, and the magnification is determined by the lenses present in the microscope. However, due to the limited wavelength of visible light, light microscopes are limited in their ability to achieve higher magnification. Typically, light microscopes can achieve magnifications of up to around 2000x.
On the other hand, electron microscopes use a beam of electrons instead of visible light. Since electrons have much shorter wavelengths than visible light, electron microscopes can achieve much higher magnification. Electron microscopes also use electromagnetic lenses instead of glass lenses, which provides better control of the electron beam. This allows electron microscopes to achieve magnifications of up to several million times.
To summarize, the advantage of electron microscopes over light microscopes is their higher magnification capabilities, which allow for more detailed and precise imaging.
