Principle

The aim of this experiment is the experimental determination of
the intersection of selected light beams which hit a convex
mirror and the image construction which follows from that. In a
preliminary experiment the characteristics of the mirror image are
determined. So it is possible to compare both
experimental results later. The experiment is
very demanding on the students’ required
experimental proficiency and on the knowledge gained by
performing it. There are no real images; the intersection of the
backward extensions of the reflected light beams lies behind the
convex mirror. Thus, it is possible to illustrate the character of
virtual images to the students and to deepen their knowledge of
virtual images on plane mirrors.

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
