Light path and focal length of a concave lens

Principle

The experiment on refraction of light by a concave lens serves, on the one hand, to strengthen the knowledge and experimental skills gained from the experiments with convex lenses. The aim of this experiment is to observe the path of light on passage through a concave lens and ...

Image construction for a concave lens

Principle

The aim of this experiment is to determine the intersection point of selected light beams incident on a planoconcave lens and thus demonstrate the possibility of image formation. First of all, in this experiment, only the course of selected light beams is observed. Only during ...

Light path of lens combinations

Principle

In the experiments concerning combinations of lenses, the students' understanding of the light path through convex and concave lenses is both strengthened and extended. The first experiments serve as direct revisions, the experiments involving the combination of a planoconcave ...

Focal length of lens combinations

Principle

In this experiment, the students strengthen their understanding of the light path through convex and concave lenses. By using a step-by-step approach proceeding from planoconvex lenses via planoconcave lenses to a combination of convex and concave lenses, the students' ...

Spherical aberration

Principle

The students become acquainted with one of the most frequent lens defects through this experiment - spherical aberration. This, in conjunction with the experiments on lens combinations, prepares the students for understanding why high quality optical apparatus always contains ...

Chromatic aberration

Principle

Spherical and chromatic aberration are the two most well-known defects of image formation associated with a lens and whose correction is achieved by incorporating expensive lens systems (achromatic) in high quality optical apparatus.
For this reason, the students should ...

Colour dispersion with a prism

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 ...

Reunification of spectral colours

Principle

In this experiment, the students investigate the possibility of reuniting coloured light to white light. In addition to strengthening their knowledge of the dispersion of light by a prism, the foundation for the understanding of additive and subtractive colour mixing is laid ...

Complementary colours

Principle

In this experiment, the students first review their knowledge of the dispersion of light by a prism and the reuniting of spectral colours with the aid of a converging lens. The main emphasis of the investigations is one the observation of the secondary colours that arise when ...

Additive colour mixing

Principle

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 ...

Subtractive colour mixing

Principle

In this experiment the students have the opportunity to investigate the possibility of subtractive colour mixing, which is based on the different spectral absorption of filters. In this way, they become acquainted with the second technically important process of colour ...

Colours of objects

Principle

Objects in our environment possess different colours. In addition they appear different in the light of evening sun than when the it is high in the sky.
In this experiment, the students investigate how this everyday phenomenon arises. On summarizing of their observations, ...

Mode of operation of the human eye (normal vision)

Principle

The experiments on accommodation in the human eye and on the defects of vision and their correction are appropriate for showing the application and validity of the laws of physics in a biological context.

In this experiment, the students should apply their knowledge about the ...

Short-sightedness and its correction

Principle

In conjunction with their investigation of the model for the short-sighted eye, the students strengthen their understanding of the light path with a convex lens. Using the example of the correction of the short-sighted eye with the aid of planoconcave lens, the useful ...

Long-sightedness an its correction

Principle

On a model of the long-sighted eye (shorter distance from the retina to the eye lens), the students should experimentally investigate the effect of long-sightedness on seeing distant and near objects. In this way, not only is their understanding of the light path through a ...
