The law of imagery is generally first theoretically derived or -
depending on the class's proficiency - simply stated and then
experimentally confirmed or tested. The experimental test can be
performed as suggested.
It is also possible to conduct the experiment in this way without
previous knowledge; however, in this case the student will not
understand why the reciprocals of f, g and b should be taken.
This is also the case when the law of imagery is only stated.
Which law holds true for images with a convex lens? Determine
which correlations exist between the focal length f, the object
distance g and the image distance b when real images are formed
with a convex lens.
