Answer:
Concept:
Compared to photons, electrons have a much shorter wavelength (2.5 pm at 200 keV). In order to image cellular structure or proteins, an electron microscope's resolution is therefore theoretically limitless.
Explanation:
- Since electrons have a far shorter wavelength than visible light, they can produce images with higher resolution than traditional light microscopes.
- It is possible to utilise electron microscopes to look at individual cells as well as their subcellular components and compartments.
- This is a result of the electron beam employed as a light source having an extremely small wavelength (0.005 mu). It is created when a metal filament is heated to a high temperature, or 50,000 volts, in a vacuum tube.
Hence, electron microscope has better resolution than other given microscopes.
