How Do Microscopes Work?
2a. DEFINE Magnification makes objects look (smaller/larger) than they
really are.
b. ESTIMATE The diameter of a microscope’s field of view is estimated
to be 0.9 mm. About how wide is an object that fills two thirds of
the field? Circle your answer.
1.8 mm
0.6 mm
0.3 mm
c. COMPARE AND CONTRAST How are magnification and resolution
different?

Understanding Main Ideas
If the statement is true, write true. If the statement is false, change the underlined word
or words to make the statement true.
1.
Cells are the basic unit of structure and function in living
things.
2.
Telescopes are instruments that can magnify
very small objects.
3.
Cells were first observed by Robert Hooke.
4.
Light microscopes use beams of electrons to
produce magnified images.
5.
Resolution is the condition when objects
appear larger than they really are.
6.
Magnification is the ability to distinguish
details on an object.
7.
If a compound microscope has a 10× lens in
its eyepiece and a 20× lens in its nosepiece, its total magnification is
100×.
