Principle

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.

Benefits


Multifunctional light box - All-in-one: Can be used for geometric optics on the table, colour mixing and on an optical bench

Extension with others sets at anytime, no additional light sources needed, recognition value for students



Tasks

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.
