In this experiment, the students should investigate the
refraction of light when it passes from air into water and
measure the angle of refraction β for given angles of incidence α.
In addition to developing the students' experimental skills in
undertaking precise and careful experiments, making careful
adjustments and measuring the angles at the optical disk, they also
learn to formulate another application of the law of
Investigation of the special case of α = 0° leads to the
recognition that laws of physics are only valid under specific
The second part of the experiment is more demanding in terms of the
experimental skills of the students. Both experiments can be seen
as a unit, but it is nevertheless possible to carry out the two
- 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
Why are reflections of objects on large water surfaces darker
than the originals?
- Investigate the behaviour of narrow light beams on passing from
air into water.
- Measure the angle of refraction as a function of the angle of
incidence when light passes from air into water.
