Principle
In this experiment, the students have the possibility of perfecting their experimental skills and strengthening their understanding of the law of refraction. In conjunction with the observation of incident light at the boundary between air and glass, the path of the light beam ...
The goal of this experiment is that the students become acquainted with special cases of the refraction of light at a prism which are important in technical applications (optical instrument construction). With the investigation and explanation of the light path as a ...
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 ...
The aim of this experiment is to investigate the dispersion of light. In the course of this, the students' understanding of the refraction of light on crossing from air to glass or glass to air, respectively, is revised with reference to the dependence of refraction on the ...
In the experiment on additive colour mixing, the students come to understand one of important, technical process for producing colour images. They should first investigate the overlapping of two different coloured light beams and then, in a further experiment, observe ...
This experiment, which should be carried out in a completely darkened room, makes great demands on the students' ability to concentrate and observe.
Benefits
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 ...
If you plan to cover both the astronomical and the Dutch telescopes in your physics course in that order, it is advisable to conduct similar experiments and to make comparisons between the two telescope types. This procedure was followed in the conception of ...
This experiment makes great demands on the students. The saccharimeter model must not only be meticulously constructed, but the measurements also require painstaking care. This is made even more difficult by the requirement for complete darkness in the physics laboratory. The ...
Illumination of an individual object create an individual shadow of the object. The shadow depends on the relative position of the light source and the object.
Observe the shadow intensity behind the illuminated object and divide it into umbra and penumbra region.
When using two extensive light sources, umbra and penumbra are formed behind opaque bodies.
Move the magnet-held lamp so that the light beam is incident at different angles. While doing so, record the respective angles of incidence and the corresponding shadow length I in a table.
