Oe 4.14 Aberrations d'images (en forme de "tonneau" ou de"barillet")

Principle

The convex lens with f = +100 mm is recommended for this experiment, so that the object and the image distances can be large enough to allow sufficient space for working with the diaphragm between the lens and the screen.

Benefits

  • Multifunctional light box - All-in-one: ...

Oe 7.1 La loupe

Principle

Although both parts of the experiment complement each other, it can sometimes be appropriate to only use one part or to let the students conduct the parts in different class periods. The first part should be performed in any case, as it conveys essential basic knowledge for ...

Oe 7.2 Conception du microscope

Principle

This experiment makes relatively great demands on the concentration and meticulousness with which the students must work in the physics laboratory, which has to be made as dark as possible. The experiment is best used as confirmation of theoretically gained knowledge about the ...

Oe 7.3 Détermination du grandissement d'un microscope

Principle

Although this experiment can be performed directly following an experiment on the construction and mode of operation of a microscope, it is recommended that it be performed separately; otherwise students might feel overly challanged.

Benefits

  • Multifunctional light box - ...

Oe 7.4 La lunette astronomique

Principle

When the students focus the telescope model on a relatively distant object in the second part of the experiment, it is advisable for them to hold it with one hand and to focus with the other. To avoid damage to the lenses, the teacher should have the students attach the parts of ...

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 7.6 Déterminination du grandissement d'une lunette

Principle

This experiment can immediately follow an experiment on the construction and function of an astronomical telescope.
 
If this experiment is performed on its own, it can easily be expanded by using the lens with f = -50 mm (no. 09820.06) as ocular, instead of ...

Oe 7.7 L'appareil photographique

Principle

This experiments makes average demands on the experimental abilities of the students. It provides them with essential insights into an optical device with which most will be familiar. Judging from past experience, students will be sufficiently motivated to investigate the ...

Oe 7.8 La profondeur de champ de l'appareil photo

Principle

The experiment can be used as an interesting extension to an experiment on the construction and function of the photographic camera. Previous experience in the form of such an experiment will enable students to safely handle the apparatus even in a (necessarily) fully darkened ...

Oe 7.9 Le projecteur de diapositives

Principle

All students will be familiar with slide projectors, and many will be interested in their construction and mode of operation. Hence they will usually be motivated for this experiment.
 
Note: This experiment is a model experiment and as such only suitable for the ...

Oe 8.1 Diffraction par un réseau

Principle

Once it has been recognised in lessons that light can be reflected and refracted just like water waves, the question poses itself of whether light has wave character. If it does, then it must be possible to demonstrate interference phenomena as with water waves.
 
This ...

Oe 8.2 Mesure de la longueur d'onde

Principle

This experiment on diffraction at an optical grating not only provides convincing proof of the ability of (visible) light to undergo interference, and hence of its wave character; but it is also well suited to determine the wavelength of selected colours of the spectrum. ...

Oe 8.3 Filtres de polarisation

Principle

After it has been demonstrated in lessons that light undergoes interference, which can only be explained in the framework of classical physics by postulating a wave character for light, the question is now investigated of whether these are transverse or longitudinal ...

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 ...

Est 1.1 Démonstration d'électrisation différente de tigespar frottement

Principle

The students should see that on rubbing different materials a negative or a positive charging results that can be demonstrated with a neon tube.

Benefits

  • Quick and easy experiment for qualitatively understanding of electrostatic phenomena

Tasks

What can we demonstrate ...
