Exploration
1. A compound microscope is a type of optical microscope.
True
False
FEEDBACK
,Well done!
2. The _____ sits below the stage and varies the field for viewing the specimen.
diaphragm
coarse adjustment knob
base
turret
FEEDBACK
Outstanding!
3. The depth of field is independent of the total magnification factor.
True
False
FEEDBACK
Right! Like field of view, the depth of field is dependent on the total magnification factor.
4. A stereoscopic microscope is also known as a _____.
scanning microscope
2-D imaging microscope
dissecting microscope
All of the above
FEEDBACK
A stereoscopic microscope is also known as a dissecting microscope.
5. An electron microscope uses _____ to illuminate an object and create an image.
, visible light
infrared light
electrons
All of the above
FEEDBACK
Good!
6. A transmission electron microscope is similar in design to a(n) _____.
scanning electron microscope
optical microscope
stereoscopic microscope
scanning probe microscope
FEEDBACK
Excellent!
7. The larger the apex of the probe, the greater the resolution of the scanning probe
microscope.
True
False
FEEDBACK
Nice! The smaller and sharper the apex of the probe, the greater the resolution of the microscope.
