Introduction - The previous chapter dealt with the refraction of light by lenses and also about the formation of various types of images by a lens for different positions of the object. In this chapter let us find out how lenses are used in optical instruments like microscopes a..

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' carri..
