microscopes Flashcards
1
Q
equation for magnification
A
image size / actual size
2
Q
light microscopes
A
- beam of lights condensed
- poor resolution (long light wavelength)
- low magnification
- coloured images
- living specimens
3
Q
resolution
A
the minimum distance between 2 objects in which they can still be viewed as separate
4
Q
SEM microscope
A
- beam of e- scatter depending on contours
- 3D shape / image
- 3D depth and texture
- thicker specimens used
5
Q
electron microscope
A
- beam of e- condensed
- high resolution (e- have short wavelength)
- higher magnification
- black and white images
- non living specimens
6
Q
magnification
A
how many times larger the image is compared to the object
7
Q
TEM microscope
A
- beam of e- through (some absorbed and others pass through)
- black and white images
- thin specimens used
- 2D shapes
- details on the internal structure of cells
