Determining the magnification of a concave lens

Principle

The theoretical derivation of the equation for the magnification dose not normally cause problems. It is therefore advisable to employ the experiment as a confirmation experiment. Then the students will have sufficient orientation as to the goal of the experiment from the very ...

Image obtained with a concave lens

Principle

The students' unsuccessful attempts at capturing images formed by a convex lens make this experiment especially interesting and motivating when they have no or only uncertain knowledge of image formation at a convex lens. However, this experiment is also highly recommended to ...

Pincushion an barrel distortion

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: ...

The magnifying glass

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 ...

The structure of a 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 ...

Determining the magnification of a 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 - ...

The astronomical telescope

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 ...

The Galilean telescope

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 ...

Determining the magnification of a telescope

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 ...

The camera

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 ...

The depth of focus of a camera

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 ...

The slide projector

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 ...

Diffraction at a grid

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 ...

Determination of the wavelength by grid diffraction

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. ...

Polarisation with filters

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 ...
