M2 Microscopes Flashcards
1
Q
Magnification
A
The degree to which the size of an image is larger than itself
2
Q
Resolution
A
The ability to distinguish between 2 objects and the amount of detail that can be seen
3
Q
TEM Microscope
A
Electrons pass through specimen
2D image
Magnification up to x500,000
Resolution 0.05-2nm
4
Q
SEM Microscopes
A
Electrons bounce off the specimen
3D image
Magnification up to x100,000
Resolution 5-50nm
5
Q
Why do electron microscopes have a very high resolution?
A
Visible light has wavelength of 400-700nm
Electrons have a wavelength of 0.004nm
The smaller the wavelength, the better the resolution
