|
|
the wavelength of the electron beams are much larger than that of visible light and therefore can detect smaller items
|
|
|
electron microscopes use quantum mechanics
|
|
|
the wavelength of the electron beams are much smaller than that of visible light and therefore can detect smaller items
|
|
|
electron microscopes use much more electricity and power enabling them to see smaller objects
|
Detailed explanation-1: -This is because electrons can have a significantly shorter wavelength (about 100, 000 times smaller) than that of visible light when accelerated through a strong electromagnetic field, thus increasing the microscope resolution by several orders of magnitude.
Detailed explanation-2: -An atom is simply too small to deflect visible light waves, which means it won’t show up under even the most powerful light-focusing microscopes, Oncel said. Yes, you can see an atom, once you understand that we can examine surfaces with beams of electrons rather than light.
Detailed explanation-3: -Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscopes. Electron microscopes can be used to examine not just whole cells, but also the subcellular structures and compartments within them.
Detailed explanation-4: -Ribosomes are only visible with the electron microscope.
Detailed explanation-5: -They have a much higher range of magnification (can detect smaller structures) They have a much higher resolution (can provide clearer and more detailed images)
