Defective accommodation in old age and its correction

Principle

In this experiment, the students should review their knowledge of the light path in the human eye and the accommodation of the eye to near and far objects. From the observation of the inadequate accommodation for divergent incident light using the model eye and therefore the ...

Day and night

Principle

This experiment does not cause any technical difficulties. However, the students often have problems because they have to imagine that they are located at the position of the observer on earth.

Benefits

  • Multifunctional light box - All-in-one: Can be used for geometric ...

The seasons

Principle

In conducting the experiment the students will not have any technical problems. But great demands will be placed on their abilities to concentrate and to observe exactly. The methodological instructions are fairly extensive, but this is justified by the fact that the students ...

Solar and lunar eclipses (with the earth-moon model)

Principle

This experiment on the occurrence of solar and lunar eclipses requires little time and places relatively slight demands on the experimental proficiency of the students.

Benefits

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

The pinhole camera

Principle

The construction of pinhole cameras is fairly easy. Usually, for students it is a lot of fun constructing and experimenting with those. It is thus advisable to let them construct a camera for homework.
The advantage of the experiment with the pinhole camera model is that ...

Luminous intensity (photometer)

Principle

The experiment, which must be conducted in a completely darkened room, is demanding both with reference to the experimental abilities of the students and also with regard to their care and exactness in making observations.

Benefits

Illuminance (inverse square law)

Principle

This experiment is suitable as both an introductory experiment and as a confirmation experiment for the validity of the inverse square law. In connection with the measurements of the side lengths of the illuminated areas the students must use their knowledge of umbra and ...

Projected image with a concave mirror

Principle

This experiment is very demanding. It does not place any great demands on the measuring accuracy of the students. But, judging from experience, students frequently have difficulties with recording the results for all the individual cases for image distance and properties of the ...

Law of imagery for a concave mirror

Principle

Generally, the law of imagery is first derived theoretically or - depending on the class situation - simply stated and then experimentally confirmed or tested. The experimental testing can be conducted as suggested above. It is also conceivable that the above procedure could be ...

Determining the magnification of a concave mirror

Principle

The theoretical determination of the equation A = B/G = b/g (magnification) does not normally cause problems. It is thus advisable to use the experiment to confirm this. Then the students will have sufficient orientation as to the goal of the experiment from the very beginning. ...

Images in a convex mirror

Principle

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

Image obtained with a convex lens

Principle

This experiment is very demanding. It does not make any great demands on the student's measuring accuracy. But, judging from past experience, understanding the individual cases for different image distances, the properties of the image as a function of object and focal length, ...

Determining the focal length of a convex lens

Principle

Two experimental variants for the determination of the focal length of a convex lens are suggested, so that at least once the students can discuss the advantages and disadvantages of each. The second variation is less accurate but easier to understand than the first. If the ...
