Could someone explain in a short and simple way the basic operation principle of a TEM?
Wikipedia, more at - http://en.wikipedia.org/wiki/Transmission_electron_microscopeTransmission electron microscopy (TEM) is an imaging technique whereby a beam of electrons is focused onto a specimen causing an enlarged version to appear on a fluorescent screen or layer of photographic film (see electron microscope), or can be detected by a CCD camera. The first practical transmission electron microscope was built by Albert Prebus and James Hillier at the University of Toronto in 1938 using concepts developed earlier by Max Knoll and Ernst Ruska.
The basic operation in science is the process of conducting experiments, making observations, and analyzing data in order to understand and explain natural phenomena.
Understanding the basic operation in science allows us to make informed decisions and advancements in various fields, such as medicine, technology, and environmental conservation.
Scientists conduct experiments by creating a hypothesis, designing a controlled experiment, gathering data through observations or measurements, and analyzing the results to draw conclusions.
Some common tools used in the basic operation of science include microscopes, thermometers, beakers, test tubes, and measuring instruments such as rulers and scales.
Yes, anyone can follow the basic operation in science by having a curious and open mind, using critical thinking skills, and following the scientific method. It is a fundamental process that can be applied in various situations and fields of study.
