A
A beam of electrons, rather than electromagnetic radiation to ‘illuminate’ the specimen.
2
Q
What do electrons behave like?
A
Waves.
They can easily be produced - using hot wire.
Focused - using electromagnetic.
And detected - using photographic film.
3
Q
A beam of electron has an effective wavelength of what?
A
Less then 1nm, so it can be used to resolve small sub-cellular ultra structure.
4
Q
Name the 2 electron microscopes?
A
Transmission electron microscopes.
Scanning electron microscopes.
