Principle

This experiment is very demanding. It does not make any great
demands on the student’s measuring accuracy. But, judging from past
experience, understanding the individual cases for different image
distances, the properties of the image as a function of object and
focal length, as well as the multitudinous technical terms often
causes the students difficulties. Dividing the experiment among
groups can make it easier methodologically. The students are
assigned to four groups. Each group performs the experiment for one
of the cases presented on the Task page. Then the results are
exchanged and Table 1 is completed by all the students. In this way
each group can conduct its special task carefully and in their own
time.
