BSC 1010L - MICROSCOPE AND CELLS EXAM QUESTIONS AND
ANSWERS WITH COMPLETE SOLUTIONS GRADED A++ LATEST
UPDATE
You will be using a ___________ microscope to comlete this lab.
Compound light
The distance between the objective and the stage is the ____________.
Working distance
Field of view is how much of the speciman you can see while looking through the
microscope.
True
When making a wet mount slide you do not have to use a coverslip if you do want
to.
False
When completing the check cell activity you will dispose of your toothpick in the
___________ and your slide in the __________.
Biohazard bucket; biohazard sharps
You are viewing a specimen with the 10x objective - what is your TOTAL
magnification?
100x ( to multiply your objective lense 10x by the ocular lense 10x to get the total
magnification)
As your magnification increases, what happens to your working distance?
, It decreases (working distance is the distance between the slide or stage and the
objective lense - it will decrease as the magnification increase)
What is the term used to describe ability of the lenses to distinguish two seperate
objects?
Resolution
Your lenses are _______________: meaning once they are in focus with one
objective they relatively in focus for all other objects and you should only need to
use the fine focus knob to bring the object into focus.
Parfocal
As the magnification of the objective lenses increase, the fied of view or diameter
of field increases. Therefore, magnification and field of view are proportional to
each other.
False
As the magnification increases, the light intensity through the ocular lenses
decreases. Therefore, magnification and light intensity are also inversely
proportional.
True
Your microscope has two types of lenses
1. objective lenses - those closest to the eyes
2. ocular lenses - those closes to the object being viewed
Ocular lenses are closest to the eyes; Objective lenses are closest to the object being
viewed
