Ans:B. Electron microscope
Electron Microscope
- These microscopes emit electron beams, not light beams, toward targets to magnify them.
- One of the microscope types contributing to the development of cellular exploration is the creation of electron microscopes.
- Innovative technologies after optical microscopes, electron microscopes allow researchers to interact with living cells, through a technology including electromagnetic lenses and electron beams.
- They are used to observe more microscopic organic structures and microorganisms.
- If the human eye can distinguish two objects separated by 0.2 mm, optical microscope can see objects separated by about 200 nm.
- Today, electron microscopes allow seeing atoms.
