22. what is the difference between an electron microscope and a compound microscope

It is a sophisticated form of microscope, which can provide a higher magnification of the object (up to 1,00,000 times or more). The electron microscope employs an electron beam emanating from a cathode, instead of light as in the compound micr..

Microscopes - A microscope is an optical device which produces a highly magnified image of very small object such as micro-organisms. Based on the design, there are two types of microscopes. They are, simple microscope and compound microscopesh..

Elementary Idea of Electron Microscope - In optical microscope, the ray of light can be bent by a lens system. By placing the object and the lens system in such a way, we control the direction of the ray to get a magnified image of the object. Since as 'electron..
