Scanning probe microscope is a branch of microscopy that forms images of surfaces using a physical probe that scans the specimen. Many scanning probe microscopes can image several interaction simultaneously to obtain an image is generally called a mode with a precision and accuracy at the atomic level or better on electronic command.

Scanning Probe Microscope is the most close Relative of Electron Microscope

Scanning Probe Microscope (SPM) is a type of microscope that uses a physical probe to scan the surface of a sample to create an image. It is a type of microscope that allows scientists to see things at a much smaller scale than is possible with traditional optical microscopes.

Comparison with Electron Microscope

Electron microscopes use beams of electrons to create images, while scanning probe microscopes use physical probes. Electron microscopes can provide much higher resolution images, but they are also much larger and more expensive than scanning probe microscopes.

Comparison with Scanning Tunneling Microscope and Atomic Force Microscope

Scanning Tunneling Microscope (STM) and Atomic Force Microscope (AFM) are both types of scanning probe microscopes. STM is used to study the electronic properties of materials by measuring the tunneling current between a sample and a probe. AFM is used to study the mechanical properties of materials by measuring the force between a sample and a probe.

Conclusion

In conclusion, while all of these microscopes are types of scanning probe microscopes, the most close relative of Electron Microscope is Scanning Probe Microscope. However, each of these microscopes has its own unique capabilities and applications and is used in different fields of study.

Read the following text and answer the following questions on the basis of the same:Electron Microscope Electron microscopes use electrons to illuminate a sample. In Transmission Electron Microscopy (TEM), electrons pass through the sample and illuminate film or a digital camera.Resolution in microscopy is limited to about half of the wavelength of the illumination source used to image the sample. Using visible light the best resolution that can be achieved by microscopes is about ~200 nm. Louis de Broglie showed that every particle or matter propagates like a wave. The wavelength of propagating electrons at a given accelerating voltage can be determined byThus, the wavelength of electrons is calculated to be 3.88 pm when the microscope is operated at 100 keV, 2. 74 pm at 200 keV and 2.24 pm at 300 keV. However, because the velocities of electrons in an electron microscope reach about 70% the speed of light with an accelerating voltage of 200 keV, there are relativistic effects on these electrons. Due to this effect, the wavelength at 100 keV, 200 keV and 300 keV in electron microscopes is 3.70 pm, 2.51 pm and 1.96 pm, respectively.Anyhow, the wavelength of electrons is much smaller than that of photons (2.5 pm at 200 keV). Thus if electron wave is used to illuminate the sample, the resolution of an electron microscope theoretically becomes unlimited. Practically, the resolution is limited to ~0.1 nm due to the objective lens system in electron microscopes. Thus, electron microscopy can resolve subcellular structures that could not be visualized using standard fluorescence microscopy.Q. Wavelength of electron as wave at accelerating voltage 200 keV is
