Smaller but crisper
HERE’S HOW
. Starting with the setup from Experiment ,
replace the +R Convex lens with the
+R Convex lens.
. Position the lenses mm apart and
repeat the observation from Experiment ,
slowly moving the eyepiece lens back and
forth until you see a clear image.
WHAT’S HAPPENING
The image that appears on the fog lens is still inverted, but it is crisper
and smaller than in Experiment . If you were to view an object that
was closer to the objective lens than the first object you viewed, the
distance between the objective lens and the eyepiece lens (fog lens)
would need to be longer to keep the image of the object in focus. If
you view an object that is further away, the distance between the
objective and the eyepiece lenses needs to be shorter.
Note the differences between Experiment and : the different
distances between the lenses, and the difference in the size and
brightness of the images on the fog filter.

TIP !
These pictures after each experiment
show a diagram of the lens setup or scope
that was just constructed. They help you
understand the path that light takes when
it travels through the various lenses in a
scope to your eye.
