1
Q
What is a Scanning Tunneling Microscope (STM)?
A
Involves bringing the tip of the probe close to the specimen.
2
Q
What is a Transmission Electron Microscope?
A
Uses a beam of electrons passed through thin slices of cells to produce a magnified image.
The maximum magnification without blurring is 1000x.
3
Q
What is the maximum magnification of an Electron Microscope?
A
500,000x magnification.
4
Q
What does a Scanning Electron Microscope do?
A
Directs electrons over the surface of the specimen to produce a 3D image.
The specimen must be dead.
5
Q
What is the function of magnets in an Electron Microscope?
A
They aim a beam of electrons at the specimen.
6
Q
What is the purpose of glass lenses in a Compound Light Microscope?
A
