How does a transmission electron microscope TEMdiffer from a scanning electron microscope SEM?
ATransmission Electron Microscope produces an image by transmitting or "shooting" electrons through an ultra thin slice of the sample, resulting in cross section views of the thing you're looking at.
A Scanning Electron Microscope produces 3D images of the sample by bombarding it with electrons and measuring the ones that bounce off.
An important difference is that an ETM has much more magnifying power than a SEM, because of the amount of electrons accelerated towards the sample.

What are the various KINDS of a microscope?
Stereomicroscope, Compound Microscope, Phase-contrast microscope, electron microscope, Scanning-electron microscope, Transmission electron microscope, Confocal-scanning microscope. THESE ARE JUST SOME. :)
What are the types of electronic microscope?
1.Scanning electron microscope (SEM) 2.Transmission electron microscope (TEM)
What are two types of electron microscopes?
Two types of electron microscopes are the scanning electron microscope, or SEM, and transmission electron microscope, or TEM.
What does a transmission electron microscope and a scanning electron microscope have in common?
These are both high resolution microscopes that both use electron beams.
What type of microscope would be best to use to look at different cells or organelles?
scanning electron microscope
What is the difference between a transmission electron microscope and a scanning electron microscope?
A transmission electron microscope uses a beam of electrons to create detailed images of the internal structure of a sample, while a scanning electron microscope uses a focused beam of electrons to create high-resolution surface images of a sample.
Which is a feature of a light microscope and is not a feature of a scanning or transmission electron microscope?
It uses a combination of lenses.
The nucleus of a cell can be viewed through what kind of microscope?
An Electron Microscope is used to study the contents of a nucleus.
What are the two types of electron mircroscopes?
The two types of electron microscopes are transmission electron microscope (TEM) and scanning electron microscope (SEM). TEMs are used to study internal structures of specimens by transmitting electrons through the sample, while SEMs are used for surface imaging by scanning a focused electron beam across the specimen.
What are the types of microscopes uses and advatanges?
Compound ,Dissection or Stereoscope, Confocal Microscope, Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM).
What is the differences between electron microscope - scanning electron microscope - transmission electron microscope and scanning tunneling electron microscope?
An electron microscope uses electrons to visualize small structures at high resolutions. A scanning electron microscope (SEM) scans a focused electron beam across a sample's surface to produce 3D images of its topography. In contrast, a transmission electron microscope (TEM) transmits electrons through a thin sample to provide detailed two-dimensional images of internal structures at atomic resolution. A scanning tunneling microscope (STM), while not a traditional electron microscope, uses a sharp tip to scan a surface at the atomic level, measuring tunneling current to create images based on electron density.
When was the scanning electron microscope invented?
The scanning electron microscope was invented in the 1960s. The first commercial scanning electron microscope was introduced in 1965 by Cambridge Instruments.
