1000 word paragraph on the use of electron
Answers
The Scanning Electron Microscope (SEM) is one of the most powerful microscopes in the field of Science. Microscopes are used to help us examine objects that are too small to be seen in a normal human eye. Since the magnifying glass was invented, it has evolved itself through many years making today’s most powerful microscope, it is also a very expensive piece of tool but it is a very useful research equipment for many applications in chemistry, medicine, molecular biology and genetics. This type of microscope allows scientist to study and observe small structural and internal cellular structures such as organelles.
The Scanning Electron Microscope creates an electronically magnified image of the sample, giving a more detailed examination because it uses a particle beam of electrons to light up the sample and make a magnified image. And throughout all existing microscopes, the SEM is more preferred being used because of it having a superior magnification than other microscopes like a light microscope, for the reason that it uses electrons that has wavelengths of around 100,000x which is shorter than photons, and it can go up to 1,000,000x magnification, while the light microscope can only go up to 1000x magnification.
This research project will show different aspects of microscopes, and how very useful they can be through many applications in modern science.
