30 times
1040 times
400 times
50 times
120sS7LT-IIb-2 - Q12
Which of the following refers to the bright circle of light when viewing a specimen through the eyepiece?
Eyepiece vision
Reflection
Blind Spot
Field of View
60sS7LT-IIb-2 - Q13
The optics of a microscope’s lenses change the orientation of the image that the observer sees. When light shines on the specimen at the bottom, it travels through or reflects off the surface, passing up through the lenses of the objectives into the eyepiece. The lenses are convex, thus light that goes through a specimen is focused and therefore magnified.
False
boolean://True
