What part of the microscope reflects light? The image above was produced by a SEM. Magnification and resolving power is the key difference between Light Microscope and Electron Microscope which is about 1000X of the magnification with resolving power of 0.2um in Light Microscope and that of Electron Microscope is 10,00,000X magnification with resolving power of 0.5nm or even less. This makes them a bit cumbersome. It is possible to observe a wide range of biological activity, such as the uptake of food, cell division and movement. electron microscopes provide higher magnifications and higher resolution images but cannot be used to view living cells. In contrast, electron microscopes are relatively larger, and need a specialized high-power source. Not be be confused with electron microscopes. What does a light microscope need to work? What is the difference between TEM SEM and light microscopes? Just to let you know, an advantage of a Transmission Electron Microscope over a Light Microscope is that you actually can observe living things, as otherwise detailed in your article.
