Electron Microscopes (EMs) function like their optical counterparts except that they use a focused beam of electrons instead of photons to image the specimen and gain information as to its structure and composition.
What is the reason why an electron microscope is used?
Advantages of electron microscopy Magnification and higher resolution as electrons rather than light waves are used, it can be used to analyze structures which cannot otherwise be seen. The resolution of electron microscopy images is in the range of up to 0.2 nm, which is 1000x more detailed than light microscopy.
Who is the inventor of the electron microscope?
Ernst Ruska, a German electrical engineer, is credited with inventing the electron microscope. The earliest electron microscope was developed in 1931, and the first commercial, mass-produced instrument became available in 1939.
Who discovered the electron microscope in 1940 class 9?
1940: Vladimir Zworykin, better known as a co-inventor of television, demonstrates the first electron microscope in the United States. Once again, the Russian emigr improves but does not, strictly speaking, invent an important electronic apparatus.
Who discovered the electron microscope and when class 9?
It was Ernst Ruska and Max Knoll, a physicist and an electrical engineer, respectively, from the University of Berlin, who created the first electron microscope in 1931. This prototype was able to produce a magnification of four-hundred-power and was the first device to show what was possible with electron microscopy.
