4. 40 the eyepiece is usually 10x the objective has a
number of magnification
So what is the total magnification?

5. Electron Microscopes This tool can produce an image million times large x. The object must be dehydrated so it is also dead.
Instead of using lenses, they use a magnetic field
to bend a beam of electrons.

6. Differences between electron microscopes
Transmission (TEM) – This tools allows the viewer to see inside structures.
Scanning (SEM) – This tools allows the viewer to see a 3 dimensional image of the structure
