Tell us about the device of an electron microscope. How many times does it enlarge the object’s image?

An electron microscope is a type of microscope that uses a beam of electrons to illuminate a sample and magnify objects significantly. It was invented in 1931 by engineers from Germany. Electron microscopes have a higher resolution than optical microscopes, which use visible electromagnetic radiation. They can get much higher magnification, up to 5 million times, whereas the best optical microscopes are limited to 2,000 times magnification.
