Electron Microscope

The electron microscope made it possible to observe the complex structure of cells and their organelles. This microscope uses a beam of electrons instead of light to magnify specimens, allowing for a much higher resolution and the ability to see much smaller structures than with a light microscope.

Working of Electron Microscope

The electron microscope works by using a beam of electrons that is focused and directed onto a specimen. The electrons are scattered or absorbed by the specimen, and the resulting image is created by collecting and processing the electrons that have passed through or bounced off the sample.

Advantages of Electron Microscope

The electron microscope has several advantages over other types of microscopes:

- High resolution: The electron microscope can achieve a resolution of up to 0.1 nm, which is much higher than the resolution of a light microscope.

- Magnification: The electron microscope can magnify specimens up to 500,000 times, allowing for the observation of much smaller structures than with a light microscope.

- Ability to see internal structures: Because electrons can penetrate the specimen, the electron microscope can reveal the internal structures of cells and organelles.

- Ability to observe non-biological specimens: The electron microscope is not limited to biological specimens and can be used to observe a wide range of materials, including metals, ceramics, and polymers.

Applications of Electron Microscope

The electron microscope has many applications in research and industry, including:

- Biological research: The electron microscope is used to study the structure and function of cells and organelles, as well as viruses and bacteria.

- Materials science: The electron microscope is used to study the structure and properties of materials at the atomic and molecular level.

- Forensics: The electron microscope can be used to analyze trace evidence and identify unknown materials.

- Nanotechnology: The electron microscope is used to study and manipulate materials at the nanoscale.

Answer is b electron because with the discovery of electron microscope in 1940,it was possible to observe and understand the. complex structure of the cell and its various organelles..and other microscopes are less powerful than electron microscope
