Gets its images by recording the electron current from a very fine pencil-like beam of electrons that is passed over a surface. a. compound light microscopes b. electron microscopes c. scanning electron microscopes d. transmission electron microscopes

An electron microscope gets its images by recording accelerated electron current using a very fine pencil-like beam of electrons as a source of illumination. Recent electron microscopes used specialized digital cameras and frame grabbers to capture images that are used to examine various biological and inorganic specimens such as biopsy samples, metals, cells and molecules. The wavelength of these electrons are shorter and have a higher resolving power, which can reveal clear structure of minute objects.

b. to discover aspects of the natural world.
