Briefly explain how a Scanning Electron Microscope (SEM) forms an image of a microscopic specimen. -
DETAILED ANSWER -Answer: An image is formed from the interactions of electrons as they reflect off
(not through) the surface of the specimen. Samples are coated in either gold or palladium to enhance
electron reflections. The reflection is seen in 3-D rendering.
