What is resolution?
Resolution is the minimum distance at which two points can be distinguished as separate.
Can live specimens can be looked at under a light microscope?
Yes

Yes
Electron microscope magnification
Up to 10 million times (10,000,000x)
Electron microscope resolution
Up to 0.5 nm
Which is more expensive? An electron microscope or a light microscope?
Electron microscope
Different types of electron microscope
- Scanning electron microscope (SEM)
- Transmission electron microscope (TEM)
What types of image does SEM and TEM produce?
SEM - Scanning Electron microscope - 3D image
TEM - Transmission Electron microscope - 2D image
How does SEM and TEM scans the specimen.
‘S’EM scans the ‘S’urface.
‘T’EM scans ‘t’hrough specimen.
