In conjunction with the experiments on the refraction of
light, this experiment is of particular importance. Knowledge of
the law of refraction is strengthened and transferred to new
contexts. At the same time, in this experiment, the students become
familiar with the lenses which are most frequently used in optical
The main focus of the first part of the experiment concerns the
observation of the course of parallel, incident light beams
converged by a convex lens and strengthening the concept of focal
In the second part of the experiment, the path of three selected
light beams is experimentally investigated and the general
prerequisites for the understanding of image formation, to be
considered later, are laid down.
The second part of the experiment is more demanding in terms of
the abilities and experimental skills required of the students.
Both experiments can be seen as indivdual units and can, likewise,
be carried out separately. This is to be recommended in the
interest of conscientious performance and further strengthening of
the students experimental skills.
Nevertheless, individual group work can also be recommesded
(each group investigating the course of different, selected light
beams then, at the end of the experiment, the data is
collected to give a total result).
- 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
How does light pass through a lens?
- Investigate the passage of light through a planoconvex
- Investigate the passage of selected light rays falling on a
