Answer 2

Answer:

The correct answer is -a scanning electron microscope

Explanation:

• Definition of a scanning electron microscope (SEM). An electron microscope called a scanning electron microscope (SEM) employs a low-energy electron beam to scan the surfaces of microorganisms.

• The Scanning Electron Microscope's Operating Principle. The scanning electron microscope employed emitted electrons as opposed to transmitted electrons, which are used by the transmission electron microscope.

• Scanning Electron Microscope (SEM) Electron Source Components At a voltage of 1–40kV, this is where electrons are created by thermal heating.

• Images from a scanning electron microscope (SEM). Figure: A SEM view of the stamens and pollen of the Tradescantia. A low-temperature scanning electron image of a soybean cyst nematode and its egg is shown in Figure.
• Applying the Scanning Electron Microscope (SEM) in energy-dispersive X-ray spectroscopy for spot chemical analysis. Used in the investigation of tiny aesthetic components.
• Scanning Electron Microscope Benefits (SEM) They are simple to use and have intuitive interfaces.
• Limitations. The scanning-transmission electron microscope (STEM) was created by combining the operating concepts of the scanning electron microscope (SEM) and the transmission electron microscope (TEM) (STEM).
