GENERAL GEOLOGY

Detailed explanation-1: -Electron microscopes allow paleontologists to study the tiniest details of the smallest fossils. X-ray machines and CT scanners reveal fossils’ internal structures.

Detailed explanation-2: -Electron microscopy uses electrons to “see” small objects in the same way that light beams let us observe our surroundings or objects in a light microscope. With EM, we can look at the feather-like scales of an insect, the internal structures of a cell, individual proteins or even individual atoms in a metal alloy.

Detailed explanation-3: -Applications of laboratory microscopes The goal of any laboratory microscope is to produce clear, high-quality images, whether an optical microscope, which uses light to generate the image, a scanning or transmission electron microscope (using electrons), or a scanning probe microscope (using a probe).

Detailed explanation-4: -Today there are two major types of electron microscopes used in clinical and biomedical research settings: the transmission electron microscope (TEM) and the scanning electron microscope (SEM); sometimes the TEM and SEM are combined in one instrument, the scanning transmission electron microscope (STEM):

Detailed explanation-5: -The main difference between SEM and TEM is that SEM creates an image by detecting reflected or knocked-off electrons, while TEM uses transmitted electrons (electrons that are passing through the sample) to create an image.
