Mélange de couleurs subjectif avec disque de Newton

Principle

Si un disque circulaire divisé en différents secteurs de couleur différente mis en rotation par un moteur suffisemment vite que l'œil ne peut plus distinguer les couleurs, une couleur mélangée est alors perçu. En variant ...

Mesure de l'indice de réfraction du verre

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 ...

Oe 3.9 Le prisme, la déviation de l'image

Principle

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 ...

Oe 4.1 Chemin de la lumière et distance focale pour une len-tille convexe

Principle

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 ...

Oe 5.1 Dispersion des couleurs par un prisme

Principle

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 ...

Mélange de couleurs addtif

Principe de l'expérience

Dans l'expérience d'addition de couleurs, les étudiants sont initiés au processus technique important permettant de produire des images en couleur.
D'abord on étudie la superposition de deux faisceaux lumineux de couleurs ...

Oe 1.7 Les phases lunaires

Principle

This experiment, which should be carried out in a completely darkened room, makes great demands on the students' ability to concentrate and observe.
 

Benefits

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

Oe 4.11 Loi de formation des images obenues avec une len- til-le convexe

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 ...

Oe 7.5 La lunette de galilée

Principle

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 ...

Oe 8.4 Rotation du plan de polarisation par une solution de- sucre

Principle

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 ...

Ot 1.1

• minimal preparation time
• light-intense halogen lamp
• easy teaching by using the demo board for demonstration
• ideal complement to analog student experiments by directly comparable devices

Ot 1.2

Principle

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.

Benefits

• minimal preparation time
• light-intense halogen lamp
• easy teaching by using the ...

Ot 1.3

Observe the shadow intensity behind the illuminated object and divide it into umbra and penumbra region.

Ot 1.4

When using two extensive light sources, umbra and penumbra are formed behind opaque bodies.

Ot 1.5

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.
