Question

whats the difference in a Transmission electron microscope,Scanning electron microscope,Compound light microscope, and a Dissecting microscope

Answer 1

anyone................... please!!!!!!!!!!!!! :(

Answer 2

A scanning electron microscope uses beams of electrons, observing the interactions of the electrons with the surface of a specimen (usually one prepared through a coating of a conductive material e.g. gold). Transmission electron microscopes on the other hand operate on ultra-slim cross-sections of specimens in which a beam of electrons is shot through a specimen and an image is constructed by how electrons pass or fail to pass through in different parts. Both of these electron-beam-driven microscopes can magnify to great levels. A compound light microscope merely uses normal light and a lens to magnify a thin translucent specimen (usually dyed). Dissecting microscopes are similar in that they use light and a lens but are usually stereoscopic (i.e. two lens are used) and made to allow magnification of 3D specimens. These light-based microscopes have a pretty large magnification range but can magnify no where near as much as the electron-beam-driven ones.
