WebA light microscope works like a refracting telescope except that the object is very close to the objective lens. An object to be studied, for example a tiny organism so small it looks like just a dot, is put on a slide, which is usually a flat piece of glass. The clips on the microscope's flat stage hold the slide in place. WebThe magnification of a lens is shown by a multiplication sign followed by the amount the lens magnifies. So a lens magnifying ten times would be ×10. The total magnification of a microscope is:...
