A scanning electron microscope will scan the surface and an electron microscope looks inside.
The light microscope use the visible light; the electron microscope use an electrons beam.
Check the link, it is a sheet describing the different types of electron and molecular geometry. It helped me a lot. ^^ electron pair geometry and molecular geometry won't be the same if there are lone pairs involved.
The difference in energy between the energy levels determines color of light emitted when an electron moves from one energy level to another.
explain
they don't.

An electron microscope uses an electron beam to illuminate a specimen and produce a magnified image. It uses an electrostatic and electomagnetic lens to magnify images. It is used to investigate the ultrastructure of bilological and inorganic specimens. A scanning tuneling microscope is used to image the surface at an atomic level. It is based on the concept of quantum tuneling. It is used in industrial and fundamental research to get atomic scale images of metal surfaces. It provides a three dimensiional profile of the surface.
For a scanning electron microscope, the most commonly used type of EM, there is no need to do anything other than stick it to an electrically conducting pad. If the sample is particularly insulating, it may be worth coating it with a very thin gold layer to prevent the specimen from charging up with electrons from the beam (this would blur the image) For a transmission electron microscope, the specimen is most commonly encased in epoxy resin before being sliced into thin enough slices that the electron beam can pass through. The sample is then placed on a fine copper grid before being placed in the microscope.
It has benefited scientists, as Ernst Ruska developed on the electron microscope, improving on the resolution. This is how he discovered Viruses and Molecules. Frits Zernike invented a microscope to study transparent and colourless specimens
Electronics is a science dealing with electrons emission electrical is a science dealing with electron flow

The to types of microscope are as following : 1. Simple microscope 2. compound microscope differences between these both is as following: simple microscope has one Len but compound microscope has two Len.
The difference in energy between the energy levels determines color of light emitted when an electron moves from one energy level to another.
explain
One may find information on medical record scanning on the site "How Stuff Works". They are have some nice articles that explain what it is, how it is done and the benefits to using it.
